Hi,
I have a program which implements IActionDelegate (i.e. it defines both run() and selectionChanged() ).
This used to work with Eclipse 3.3.2/EMF 2.3, but it fails with Eclipse 3.4M7/EMF 2.4M7 , because
according to the implemented selectionChanged(), selection is always null, even if something is selection
when calling the method. There are no compile/build errors.
I've attached the backtrace and the part which implements IActionDelegate.
Am I doing something wrong?
Regards,
Rene

I've changed the file a bit to look like CreateDynamicInstanceAction (unfinalize
method parameters, extend ActionDelegate, add a constructor which calls super() ),
but the parameter 'selection' is still null upon entering selectionChanged().
Any ideas?

Rene,
Maybe try setting a breakpoint in the selectionChanged method of each
and see how they are called...

I've regenerated all Java files but this doesn't help either. I did
find out that meta.presentation.MetaEditor.handleChangedResources()
(also regenerated) is never called when pressing the activating keys
(Ctrl+Alt+A in my case).
Could the problem be in some project file? (see the attachment).

Rene,
It's handle activate that should be called and it should properly set
the selection that's applied to your action; handleChangedResources
should only be called if there are resource deltas in the workspace that
affect the files being edited.

This is a multi-part message in MIME format.

I completely regenerated the model, edit, and editor code and resources to be sure that
there were no leftovers which could cause problems, but the selection returned from
IActionDelegate.selectionChanged() is still null.
Upon loading the model, the topmost element is selected, getContentOutlinePage()
tells that this is an org.eclipse.emf.ecore.xmi.impl.XMIResourceImpl, which causes
handleContentOutlineSelection() to ignore this element, because it is not an instance
of IStructuredSelection.
If I click on the element of type Meta.meta (the first child of XMIResourceImpl),
these listeners are informed:
org.eclipse.emf.edit.ui.action.DeleteAction@13c339f
org.eclipse.emf.edit.ui.action.CutAction@1612600
org.eclipse.emf.edit.ui.action.CopyAction@105e560
org.eclipse.emf.edit.ui.action.PasteAction@1641c0
org.eclipse.emf.edit.ui.action.ValidateAction@136ab79
org.eclipse.emf.edit.ui.action.ControlAction@33c1aa
meta.presentation.MetaActionBarContributor@1efa3e7
org.eclipse.ui.internal.AbstractSelectionService$1@1f1cc1a
org.eclipse.ui.internal.AbstractSelectionService$2@18eef25
org.eclipse.ui.internal.AbstractSelectionService$1@f67d81
org.eclipse.ui.internal.AbstractSelectionService$2@a9a1ac
Are these listeners involved in setting the selection, if not,
what sets the selection?
I've added the metamodel, a dummy sample model, and some of
the custom add-on code which is contained in its own project.
Does anyone see any errors in it?

Rene,
When the generated editor's setSelection is called, anything listening
to the editor's selection provider should be notified. All those
actions you mention listen for that. I have two days of e4
<http://wiki.eclipse.org/E4/Summit>meetings, so I'm not sure when I will
get to trying out your example... Given that the selection is getting
to all these other actions, there must be something specific about your
action that's different from all these others. Is your action in this
sample code?

Yes, just press Ctrl+Alt+A when the element 'meta' in the sample model is
selected. I get 'selection=null' in the console.

Rene,
The room I was in today didn't allow newsgroup access. I'll hopefully
get a chance to try this tomorrow.

Rene,
I don't see anything obviously wrong with the code, but this confuses me:
<extension
point="org.eclipse.ui.popupMenus">
<objectContribution
adaptable="false"
id="mt-test.diagram.custom.objectContribution1"
objectClass="meta.custom.MetaEditor">
<action
class="meta.custom.MetaEditor"
Compare that to this where objectClass on <objectContribution> is the
type of object to which the popup applies:
<objectContribution
id="org.eclipse.emf.ecore.editor.CreateDynamicInstance"
objectClass="org.eclipse.emf.ecore.EClass">
<action
id="org.eclipse.emf.ecore.editor.CreateDynamicInstanceAction "
label="%_UI_CreateDynamicInstance_menu_item"
menubarPath="additions"
class="org.eclipse.emf.ecore.action.CreateDynamicInstanceAction "
It's like your action only applies to itself. To me that seems more
than a little suspect...

Hi Ed,
I have it working again :) The only thing is that the hotkey (Ctrl+Alt+A)
doesn't work, but selecting the action from the context menu does. I suspect
it's because the key is not properly 'connected' in the plugin.xml file.
It's not that bad, since the tool is not of commercial quality anyway.
