Cannot reopen diagram representation after eclipse restart

Question

Hi, I can't seem to resolve this issue. I create an emf genmodel from my xml schema.
next I do generate-all. I also created a viewpoint specification for model. I tried both: 1. export the projects as deployable plugins & fragments and 2. run-as eclipse application. Either way I can use the new generated wizard to create my model and I can edit the new model in the generated model editor and I can enable the viewpoint and create a representation diagram for the new model.
The problem I have is after I save the diagram, if I exit eclipse or close and re-open the project, the diagram can no longer be opened. I can still use create-representation
to create a new diagram for the same model by the old diagram is no longer usable.
I tried the Example basicFamily model and everything works fine.
I find the same behavior on eclipse Mars and eclipse Luna using Sirius 3.0
Any Ideas on how to debug this or what the problem could be?
Thanks,
Rob

This indicates that the link to the semantic model have been serialized
without issue (like in your preceding post).

I think you should look into the aird in text mode to see how the link
between your diagram and the semantic element on which you created it
has been serialized:
<ownedRepresentations xmi:type="diagram:DSemanticDiagram"
xmi:id="_mKjv0BXPEeWwcbvMkwT-CQ" name="MyDiagramName">
<target xmi:type="ecore:EPackage" href="YouSemanticModel.xxx#/"/>
</ownedRepresentations>
