Description Laurent Redor CLA 2015-01-12 11:02:55 EST 
+++ This bug was initially created as a clone of Bug #452681 +++

Using the attached example :

1. open My.ecore
2. Expand the My.ecore from Model Explorer to see the diagram under the root package.
3. In the My.ecore opened with the Sample Ecore Model Editor, copy and paste "c1" then save
4. Under My.ecore in Model Explorer, the root EPackage is collapsed and when you expand it the diagram does not appears. It appears only under the .aird hierarchy. We must close and reopen the Modeling Project to see again the diagram under root EPackage in Model Explorer or do another changes in the Sample Ecore Model Editor.

Belqassim, could you precise your errors ?

When I modified the semantic model by using the editor, the representation file dispears from the Model Explorer view after session reload (after saving the model).
Comment 6 Laurent Redor CLA 2015-01-20 03:53:13 EST 
The fix is OK on Juno but is KO on Luna. There is probably a change in org.eclipse.emf.ecore.util.ECrossReferenceAdapter.
Comment 7 Laurent Redor CLA 2015-01-20 11:09:57 EST 
Indeed, since the bugzilla 400891, the proxyMap is no longer used if the resolve() method returns true. In this case, we must iterate on all crossReferences to retrieve corresponding proxies.
