What does CDOUtil.isStaleObject(..) return for that object (the one that you can get without an exception)? Can you
provide me with a small test case to reproduce it?
You can also compare with Bugzilla_279982_Test.testBugzilla_279982_Single().

Hm, we could let the proxy handle calls to equals() such that "arg0 == this", instead of throwing an
ObjectNotFoundException. Please submit an enhancement request.

Dear Christophe,
Sorry for posting this question here.
I need to manage palette in papyrus programmatically when user is working on the diagram editor. When I select an element in the diagram editor, I need to refresh the palette. So I want to be able to add/remove some entries or set them as visible or invisible on the palette.
I found your reply to Dave posted in July 2009 about changing palette icons. You mentioned that its possible to access to paletteRoot through the editor: XXXDiagramEditor.getEditDomain().getpaletteViewer().getpaletteRoot()
Is the paletteRoot what I need for this case?
I traced the code and I guess the XXXDiagramEditor is UMLDiagramEditor. But the problem is that I don't know how to access to the UMLDiagramEditor:( can you please guide me?
Thanks and regards,
Leila

I think it's better to mail them directly, if you need someone's
specific attention. Many people watching this forum will frown reading a
question about GMF/GEF here. Please mail me directly or on the GMF
forum, I will try to find the answer for you.
