Antoher "unable to open editor, unknown ID" problem [message #441892]

Hi...

sorry for posting an old problem again, but I coulnd't find any working solution for my problem in the threads... so please give me some advice if you have..

I'm trying to develop a GUI based on RCP. Right know I'd like to create an editor, which pops up, when an item of the tree viewer is selected by choosing a menu entry.
But I can't get the editor working, cause I got the PartInitException: Unable to open editor, unknown editor ID.
The steps I've made so far are as follows:
- creating the editor class, which is subclass of EditorPart (TestEditor)
- creating the editor input class, which implements IEditorInput (TestEditorInput)
- specify the action class(TestAction), to supply the menu entry on the GUI, which also calls the function

page.openEditor(input,TestEditor.ID)

This ID is defined in the editor class as follows:
public static String ID = "test.editor.testEditor"

and also defined in the plugin.xml for an editor extension.

Below I paste the failure report I got, when I tried to choose the menu

Can someone please help me? I'm quite desperate..:-(

Thank you very much in advance

Regards
Paul

Paul, did you create the testEditorActionBarContributor which implements
IActionBarContributor - because you need to.

I didn't create any ActionBarContributor bcs I don't what it is for...
I read a book about RCP, showing examples how to create an editor. This examples shows only these 3 classes I mentioned before.
Moreover, I've just tried to follow your suggestion, but I got directly following message for implementing IActionBarContributor:
Discouraged access: The type IActionBarContributor is not accessible due to restriction on required
library C:\eclipse\plugins\org.eclipse.ui.workbench_3.2.0.I20051214- 1200.jar

Sorry for bothering you...but could you please explain more, what I can do with it?
Thanks before..

Best Regards

you define ID 'test.editor.testEditor', and try open ID test.testEditor

Never heard of this one. Sounds like some sort of security access
restriction. The IActionBarContributor doesn't require anything to be
done to it just that it be created. Also the tooltip text in the
IEditor part needs to have something returned other then null. I am
still learing RCP but I have all my editors opening when I complete all
I have stated.

There is a good example HYPERBOLA which the authors have written a book
about which is good to get a starting idea of what is happening. Its in
the RCP examples on the Eclipse site.

see you first message in this thread
you have this in code :

public static String ID = "test.editor.testEditor"

and this is from error message
org.eclipse.ui.PartInitException: Unable to open editor, unknown editor ID:
test.testEditor

Hi...

the example of HYPERBOLA is exactly the example from the book I meant before...and I followed the steps as stated in it, but I couldn't get it working..unfortunately the book didn't mention anything about such case..

From the error report I got, I tried to follow up the first line, which is:

PartInitException:Unable to open editor, unknown editor ID: net.sf.bibxmleditor.ui.modifyEditor
at org.eclipse.ui.internal.EditorManager.openEditor(EditorManag er.java:630)
....

From the class EditorManager line 630 are following codes to see:

IEditorRegistry reg = getEditorRegistry();
EditorDescriptor desc = (EditorDescriptor) reg.findEditor(editorId);
if (desc == null) {
throw new PartInitException(
NLS.bind(WorkbenchMessages.EditorManager_unknownEditorIDMess age,editorId ));
}

I suppose that the EditorRegistry couldn' find the editor. Do you have any idea, what this could mean, and how I can solve this problem?
Thanks in advance

Paul,
your error
org.eclipse.ui.PartInitException: Unable to open editor, unknown editor ID:
test.testEditor
tell that you try open unknown editor ID - you have defined another ID
or your definition (editors extension point) is invalid
check double your extension point

send your extension point - maybe it isn't ID problem
your extension definition is complete wrong (probably)

it is fine, but invalid ID tell that eclipse can't find this ID
maybe , plugin with editor extension isn't included or
extension is commented in plugin.xml and eclipse can't find this extension

Do you know something about the Editor Registry? Because the part of codes that causes this problem is this one:
IEditorRegistry reg = getEditorRegistry();
EditorDescriptor desc = (EditorDescriptor) reg.findEditor(editorId);
if (desc == null) {
throw new PartInitException(
NLS.bind(WorkbenchMessages.EditorManager_unknownEditorIDMess age,editorId ));
}

Paul,
it is clear from your error - eclipse doesn't recognize your ID
it can be that you mistake type id, noninculde plugin, mistake in extension
try debug your code for more information
i know that editors extension work fine, because i use it

Have you specified the 'icon' attribute in the plugin extension editor for your editor? It may sound strange, but the icon attribute is required if you supply your own class in the 'class' attribute to implement the IEditorPart interface.

Well, the icon itself does not need to exist, but the 'icon' attribute's field must not be empty. Without the icon defined, your editor never gets into the editor registry when the plugin extensions are read, so an attempt later to retrieve this editor by its id fails, even though the editor ID is correct.

I always find that its safer to use the "Extensions" tab on the
plugin.xml when, rather than entering directly into the plugin.xml, when
you're adding in extensions. Quite a few of the eclipse extensions
have templates that will help you to set things up,
org.eclipse.ui.editors being one of them.

Hope you have fun using Eclipse, I know it makes my life easier... most
of the time :)

Hello

Had the same exception - the mistake was to forget to set a icon for the editor in the extension point declared in plugin.xml. Hope that helps somebody....

Thanks a lot....

I also had the problem regarding opening the editor and I found it was not working just because of the absence of icon selection. So your suggesion has solved my problem but I may ask you for further help. Thank you Very much once again.
