I am getting this error message while running an editor I am developing:
WARNING: Prevented recursive attempt to activate part
DocumentEditor.SchedulePropertyEditor while still in the middle of
activating part DocumentEditor.scheduleEditor.
Note DocumentEditor.SchedulePropertyEditor is a subclass of ViewPart and
DocumentEditor.scheduleEditor is a subclass of the related EditorPart.
The ISelectionProvider implementation is a different class. This new editor
is similar to an older editor that is working fine and uses some of the same
code.
The old editor extends MultiPageEditorPart and implements ISelectionProvider
in the same class. The old editor also uses a very similar ViewPart
subclass.
The old editor has a SWT Swing bridge editor window of graphic objects and a
SashForm based property view.
The new editor has a SWT editor window of graphic objects and a SashForm
property view.
Both editors use tha same SashForm property view class called PropertyPane.
When a graphic object is selected in the new editor its properties appear in
the property view when a property is modified and when another graphic
object is selected the recursion error occurs in the new editor and not in
the old editor. The stack trace shows a dispose SWT Text or DropDown
object being called in the SashForm property view class.
Also selection events do not always behave consistently. Somethimes the
properties do not appear when selected and sometimes the property
modification is lost.
The only related difference I can see between the two editors is that the
ISelectionProvider is in a separate class from the EditorPart in the new
editor.
I noted in the Eclipse bug list that seven recent bug reports are related to
this kind of error message, but for different components.
Does any one have any other ideas?
Should I report this as a bug?
This is the stack trace.

Ron,
You also asked this same question on the SWT newsgroup. In general, if
you must post to multiple newsgroups, please do so with a single posting
addressed to all the groups so an answer on one group will appear on all
groups (thereby reducing the workload for people answering questions).
Not that I understand the details here, but one potential solution is to
use this type of approach:
getSite().getShell().getDisplay().asyncExec
(new Runnable()
{
public void run()
{
doSomethingALittleLater();
}
});

Note DocumentEditor.SchedulePropertyEditor is a subclass of ViewPart and
DocumentEditor.scheduleEditor is a subclass of the related EditorPart.
The ISelectionProvider implementation is a different class. This new editor
is similar to an older editor that is working fine and uses some of the same

The old editor extends MultiPageEditorPart and implements ISelectionProvider
in the same class. The old editor also uses a very similar ViewPart
subclass.
The old editor has a SWT Swing bridge editor window of graphic objects and a
SashForm based property view.
The new editor has a SWT editor window of graphic objects and a SashForm
property view.
Both editors use tha same SashForm property view class called PropertyPane.
When a graphic object is selected in the new editor its properties appear in
the property view when a property is modified and when another graphic
object is selected the recursion error occurs in the new editor and not in
the old editor. The stack trace shows a dispose SWT Text or DropDown
object being called in the SashForm property view class.
Also selection events do not always behave consistently. Somethimes the
properties do not appear when selected and sometimes the property
modification is lost.
The only related difference I can see between the two editors is that the
ISelectionProvider is in a separate class from the EditorPart in the new
editor.
I noted in the Eclipse bug list that seven recent bug reports are related to
this kind of error message, but for different components.
Does any one have any other ideas?
Should I report this as a bug?

This is my first posting so I am still getting used to the system. I =
originally posted to the SWT group because the web page did not offer a =
link to the platform group. I then realized I should have posted to the =
platform group. Later I realized the original title was not good so I =
reposted the message with a better title to both groups. =20
As for the asyncExec
suggestion the code is already in a syncExec runnable.
Thanks for the advice.

Ron,
You also asked this same question on the SWT newsgroup. In general, =
if you must post to multiple newsgroups, please do so with a single =
posting addressed to all the groups so an answer on one group will =
appear on all groups (thereby reducing the workload for people answering =
questions). =20
Not that I understand the details here, but one potential solution is =
to use this type of approach:
getSite().getShell().getDisplay().asyncExec
(new Runnable()
{
public void run()
{
doSomethingALittleLater();
}
});

I am getting this error message while running an editor I am developing:
WARNING: Prevented recursive attempt to activate part
DocumentEditor.SchedulePropertyEditor while still in the middle of
activating part DocumentEditor.scheduleEditor.
Note DocumentEditor.SchedulePropertyEditor is a subclass of ViewPart and
DocumentEditor.scheduleEditor is a subclass of the related EditorPart.
The ISelectionProvider implementation is a different class. This new =
editor
is similar to an older editor that is working fine and uses some of the =
same
code.
The old editor extends MultiPageEditorPart and implements =
ISelectionProvider
in the same class. The old editor also uses a very similar ViewPart
subclass.
The old editor has a SWT Swing bridge editor window of graphic objects =
and a
SashForm based property view.
The new editor has a SWT editor window of graphic objects and a SashForm
property view.
Both editors use tha same SashForm property view class called =
PropertyPane.
When a graphic object is selected in the new editor its properties =
appear in
the property view when a property is modified and when another graphic
object is selected the recursion error occurs in the new editor and not =
in
the old editor. The stack trace shows a dispose SWT Text or DropDown
object being called in the SashForm property view class.
Also selection events do not always behave consistently. Somethimes the
properties do not appear when selected and sometimes the property
modification is lost.
The only related difference I can see between the two editors is that =
the
ISelectionProvider is in a separate class from the EditorPart in the new
editor.
I noted in the Eclipse bug list that seven recent bug reports are =
related to
this kind of error message, but for different components.
Does any one have any other ideas?
Should I report this as a bug?
This is the stack trace.

editor
is similar to an older editor that is working fine and uses some of the =
same
code.
The old editor extends MultiPageEditorPart and implements =
ISelectionProvider
in the same class. The old editor also uses a very similar ViewPart
subclass.
The old editor has a SWT Swing bridge editor window of graphic objects =
and a
SashForm based property view.
The new editor has a SWT editor window of graphic objects and a SashForm
property view.
Both editors use tha same SashForm property view class called =
PropertyPane.
When a graphic object is selected in the new editor its properties =
appear in
the property view when a property is modified and when another graphic
object is selected the recursion error occurs in the new editor and not =
in
the old editor. The stack trace shows a dispose SWT Text or DropDown
object being called in the SashForm property view class.
Also selection events do not always behave consistently. Somethimes the
properties do not appear when selected and sometimes the property
modification is lost.
The only related difference I can see between the two editors is that =
the
ISelectionProvider is in a separate class from the EditorPart in the new
editor.
I noted in the Eclipse bug list that seven recent bug reports are =
related to
this kind of error message, but for different components.
Does any one have any other ideas?
Should I report this as a bug?
This is the stack trace.

Ron,
No big deal. I just give people what is hopefully a friendly reminder. :-)
I will again qualify what I say as a stab in the dark, but synchExec
blocks the caller whereas asynchExec allows the caller to complete, so
using the later might allow you to break whatever cycle is occurring.

Ron,<br>

You also asked this same question on the SWT newsgroup. In general, if
you must post to multiple newsgroups, please do so with a single
posting addressed to all the groups so an answer on one group will
appear on all groups (thereby reducing the workload for people
answering questions). <br>
<br>
Not that I understand the details here, but one potential solution is
to use this type of approach:<br>
<br>
<small> getSite().getShell().getDisplay().asyncExec<br>
(new Runnable()<br>
{<br>
public void run()<br>

The ISelectionProvider implementation is a different class. This new editor

SashForm based property view.
The new editor has a SWT editor window of graphic objects and a SashForm

Both editors use tha same SashForm property view class called PropertyPane.
When a graphic object is selected in the new editor its properties appear in
the property view when a property is modified and when another graphic
object is selected the recursion error occurs in the new editor and not in
the old editor. The stack trace shows a dispose SWT Text or DropDown
object being called in the SashForm property view class.
Also selection events do not always behave consistently. Somethimes the
properties do not appear when selected and sometimes the property
modification is lost.
The only related difference I can see between the two editors is that the
ISelectionProvider is in a separate class from the EditorPart in the new
editor.
I noted in the Eclipse bug list that seven recent bug reports are related to
this kind of error message, but for different components.
Does any one have any other ideas?
Should I report this as a bug?

Ed, thanks for the idea. I tried the asyncExec while making the run =
methods synchronized and the recursion exception went away. However the =
property view "get" methods are not working when properties are =
modified.=20
I tried merging the ISelectionProvider class with the EditorPart class. =
Those functions being in separate classes was the only noticable =
difference between the old editor and the new editor. Merging the =
classes did not make any difference.

Ron,
No big deal. I just give people what is hopefully a friendly =
reminder. :-)
I will again qualify what I say as a stab in the dark, but synchExec =
blocks the caller whereas asynchExec allows the caller to complete, so =
using the later might allow you to break whatever cycle is occurring.

As for the asyncExec

<BLOCKQUOTE cite=3Dmidev2v8c$aul$1@build.eclipse.org =
type=3D"cite"><PRE wrap=3D"">I am getting this error message while =
running an editor I am developing:
WARNING: Prevented recursive attempt to activate part
DocumentEditor.SchedulePropertyEditor while still in the middle of
activating part DocumentEditor.scheduleEditor.
Note DocumentEditor.SchedulePropertyEditor is a subclass of ViewPart and
DocumentEditor.scheduleEditor is a subclass of the related EditorPart.
The ISelectionProvider implementation is a different class. This new =
editor
is similar to an older editor that is working fine and uses some of the =
same
code.
The old editor extends MultiPageEditorPart and implements =
ISelectionProvider
in the same class. The old editor also uses a very similar ViewPart
subclass.
The old editor has a SWT Swing bridge editor window of graphic objects =
and a
SashForm based property view.
The new editor has a SWT editor window of graphic objects and a SashForm
property view.
Both editors use tha same SashForm property view class called =
PropertyPane.
When a graphic object is selected in the new editor its properties =
appear in
the property view when a property is modified and when another graphic
object is selected the recursion error occurs in the new editor and not =
in
the old editor. The stack trace shows a dispose SWT Text or DropDown
object being called in the SashForm property view class.
Also selection events do not always behave consistently. Somethimes the
properties do not appear when selected and sometimes the property
modification is lost.
The only related difference I can see between the two editors is that =
the
ISelectionProvider is in a separate class from the EditorPart in the new
editor.
I noted in the Eclipse bug list that seven recent bug reports are =
related to
this kind of error message, but for different components.
Does any one have any other ideas?
Should I report this as a bug?
This is the stack trace.

Ron,
Unfortunately I don't know enough about how your application is
structured to offer detailed advice on this. :-(
I know that in the generated EMF editors we call
PropertySheetPage.refresh whenever a command is executed (i.e., whenever
the model state changes):
commandStack.addCommandStackListener
(new CommandStackListener()
{
public void commandStackChanged(final EventObject event)
{
getContainer().getDisplay().asyncExec
(new Runnable()
{
public void run()
{
firePropertyChange(IEditorPart.PROP_DIRTY);
// Try to select the affected objects.
//
Command mostRecentCommand =
((CommandStack)event.getSource()).getMostRecentCommand();
if (mostRecentCommand != null)
{
setSelectionToViewer(mostRecentCommand.getAffectedObjects()) ;
}
if (propertySheetPage != null &&
!propertySheetPage.getControl().isDisposed())
{
*propertySheetPage.refresh();*
}
}
});
}
});

Ron,<br>
<br>
You also asked this same question on the SWT newsgroup. In general, if
you must post to multiple newsgroups, please do so with a single
posting addressed to all the groups so an answer on one group will
appear on all groups (thereby reducing the workload for people
answering questions). <br>
<br>
Not that I understand the details here, but one potential solution is
to use this type of approach:<br>
<br>
<small>
getSite().getShell().getDisplay().asyncExec<br>
(new Runnable()<br>
{<br>

<pre wrap="">I am getting this error message while running an editor I am developing:
WARNING: Prevented recursive attempt to activate part
DocumentEditor.SchedulePropertyEditor while still in the middle of
activating part DocumentEditor.scheduleEditor.
Note DocumentEditor.SchedulePropertyEditor is a subclass of ViewPart and
DocumentEditor.scheduleEditor is a subclass of the related EditorPart.
The ISelectionProvider implementation is a different class. This new editor
is similar to an older editor that is working fine and uses some of the same
code.
The old editor extends MultiPageEditorPart and implements ISelectionProvider
in the same class. The old editor also uses a very similar ViewPart
subclass.
The old editor has a SWT Swing bridge editor window of graphic objects and a
SashForm based property view.
The new editor has a SWT editor window of graphic objects and a SashForm
property view.
Both editors use tha same SashForm property view class called PropertyPane.
When a graphic object is selected in the new editor its properties appear in
the property view when a property is modified and when another graphic
object is selected the recursion error occurs in the new editor and not in
the old editor. The stack trace shows a dispose SWT Text or DropDown
object being called in the SashForm property view class.
Also selection events do not always behave consistently. Somethimes the
properties do not appear when selected and sometimes the property
modification is lost.
The only related difference I can see between the two editors is that the
ISelectionProvider is in a separate class from the EditorPart in the new
editor.
I noted in the Eclipse bug list that seven recent bug reports are related to
this kind of error message, but for different components.
Does any one have any other ideas?
Should I report this as a bug?
This is the stack trace.

Thanks again, Ed.
It is kind of hard to provide meaningful details. The ProperyPane is =
custom property editor derived from a SashForm. The same class is used =
in the old and new editors. It works in the old editor, but not in the =
new one. I am going to do a detailed comparison of the event reponse of =
both editors. When I finish I will post my findings.

DocumentEditor.scheduleEditor is a subclass of the related EditorPart.
The ISelectionProvider implementation is a different class. This new =
editor
is similar to an older editor that is working fine and uses some of the =
same
code.
The old editor extends MultiPageEditorPart and implements =
ISelectionProvider
in the same class. The old editor also uses a very similar ViewPart
subclass.
The old editor has a SWT Swing bridge editor window of graphic objects =
and a
SashForm based property view.
The new editor has a SWT editor window of graphic objects and a SashForm
property view.
Both editors use tha same SashForm property view class called =
PropertyPane.
When a graphic object is selected in the new editor its properties =
appear in
the property view when a property is modified and when another graphic
object is selected the recursion error occurs in the new editor and not =
in
the old editor. The stack trace shows a dispose SWT Text or DropDown
object being called in the SashForm property view class.
Also selection events do not always behave consistently. Somethimes the
properties do not appear when selected and sometimes the property
modification is lost.
The only related difference I can see between the two editors is that =
the
ISelectionProvider is in a separate class from the EditorPart in the new
editor.
I noted in the Eclipse bug list that seven recent bug reports are =
related to
this kind of error message, but for different components.
Does any one have any other ideas?
Should I report this as a bug?
This is the stack trace.

Hi, I've got the same Warning :

activate part org.eclipse.ui.views.ContentOutline while still in the
middle of activating part com.mds.editor.editor
when I open an editor from my GEF editor by the command
IEditorPart editor = IDE.openEditor(page,editorInput,EDITOR_ID,true);
and when I come back to the first editor.
I've tried to open it with a asyncExec but it does not make any change.
Maybe it's the way I open the editor which is wrong.
Regards.

Regards.

using asyncExec instead of sync seemed to solve the recursion problem. =
I also found the new editor was missing a setFocus function that the old =
editor had. This error caused a lot of my property modification =
problems that were based on focus lost. The new editor derived from =
EditorPart and the old editor derived from MultiPageEditorPart.=20

This is my first posting so I am still getting used to the system. I =
originally posted to the SWT group because the web page did not offer a =
link to the platform group. I then realized I should have posted to the =
platform group. Later I realized the original title was not good so I =
reposted the message with a better title to both groups. =20
As for the asyncExec
suggestion the code is already in a syncExec runnable.
Thanks for the advice.

Ron,
You also asked this same question on the SWT newsgroup. In general, =
if you must post to multiple newsgroups, please do so with a single =
posting addressed to all the groups so an answer on one group will =
appear on all groups (thereby reducing the workload for people answering =
questions). =20
Not that I understand the details here, but one potential solution =
is to use this type of approach:
getSite().getShell().getDisplay().asyncExec
(new Runnable()
{
public void run()
{
doSomethingALittleLater();
}
});

I am getting this error message while running an editor I am developing:
WARNING: Prevented recursive attempt to activate part
DocumentEditor.SchedulePropertyEditor while still in the middle of
activating part DocumentEditor.scheduleEditor.
Note DocumentEditor.SchedulePropertyEditor is a subclass of ViewPart and
DocumentEditor.scheduleEditor is a subclass of the related EditorPart.
The ISelectionProvider implementation is a different class. This new =
editor
is similar to an older editor that is working fine and uses some of the =
same
code.
The old editor extends MultiPageEditorPart and implements =
ISelectionProvider
in the same class. The old editor also uses a very similar ViewPart
subclass.
The old editor has a SWT Swing bridge editor window of graphic objects =
and a
SashForm based property view.
The new editor has a SWT editor window of graphic objects and a SashForm
property view.
Both editors use tha same SashForm property view class called =
PropertyPane.
When a graphic object is selected in the new editor its properties =
appear in
the property view when a property is modified and when another graphic
object is selected the recursion error occurs in the new editor and not =
in
the old editor. The stack trace shows a dispose SWT Text or DropDown
object being called in the SashForm property view class.
Also selection events do not always behave consistently. Somethimes the
properties do not appear when selected and sometimes the property
modification is lost.
The only related difference I can see between the two editors is that =
the
ISelectionProvider is in a separate class from the EditorPart in the new
editor.
I noted in the Eclipse bug list that seven recent bug reports are =
related to
this kind of error message, but for different components.
Does any one have any other ideas?
Should I report this as a bug?
This is the stack trace.

<BLOCKQUOTE cite=3Dmidev2v8c$aul$1@build.eclipse.org =
type=3D"cite"><PRE wrap=3D"">I am getting this error message while =
running an editor I am developing:
WARNING: Prevented recursive attempt to activate part
DocumentEditor.SchedulePropertyEditor while still in the middle of
activating part DocumentEditor.scheduleEditor.
Note DocumentEditor.SchedulePropertyEditor is a subclass of ViewPart and
DocumentEditor.scheduleEditor is a subclass of the related EditorPart.
The ISelectionProvider implementation is a different class. This new =
editor
is similar to an older editor that is working fine and uses some of the =
same
code.
The old editor extends MultiPageEditorPart and implements =
ISelectionProvider
in the same class. The old editor also uses a very similar ViewPart
subclass.
The old editor has a SWT Swing bridge editor window of graphic objects =
and a
SashForm based property view.
The new editor has a SWT editor window of graphic objects and a SashForm
property view.
Both editors use tha same SashForm property view class called =
PropertyPane.
When a graphic object is selected in the new editor its properties =
appear in
the property view when a property is modified and when another graphic
object is selected the recursion error occurs in the new editor and not =
in
the old editor. The stack trace shows a dispose SWT Text or DropDown
object being called in the SashForm property view class.
Also selection events do not always behave consistently. Somethimes the
properties do not appear when selected and sometimes the property
modification is lost.
The only related difference I can see between the two editors is that =
the
ISelectionProvider is in a separate class from the EditorPart in the new
editor.
I noted in the Eclipse bug list that seven recent bug reports are =
related to
this kind of error message, but for different components.
Does any one have any other ideas?
Should I report this as a bug?
This is the stack trace.
