I am trying to compare 2 models using EMF CompareUI release 2.1M4.
For my custom model I have created an editor containing "Non-Model Intermediary View Objects". These objects are more or less vitual folders containing the real eCore objects. The whole concept is described in the "EMF - Eclipse Modeling Framework - Second Edition - chapter 19.2.3". This works fine.
When I try to compare the model objects, for a standard object the custom editor is opened in a TreeContentMergeViewer using my custom editor. But when I select a feature that is contained within a "Non-Model Intermediary View Object", a default text compare editor is used, that contains the wrong data.
As far as I understand the problem is, that the CompareUI is unable to determine the correct content type from the ITypedElement for the parent "Non-Model Intermediary View Object" (see CompareUIPlugin.getCommonType() and CompareUIPlugin.getTypes() ). So it uses ITypedElement.TEXT_TYPE as fallback content type instead.
My question is, how can I display a TreeContentMergeViewer using my custom editor, when "Non-Model Intermediary View Objects" are used:
A) Is it a bug in CompareUI?
B) In order to diplay my custom editor, should my "Non-Model Intermediary View Objects" return ITypedElement.FOLDER_TYPE as their type? How do I do that?
C) Do I have to override e.g. DiffElement in order make CompareUI determine the real ecore parent or correct type? If yes, what do I have exactly to do?
Thanks for your help...
