cannot reopen diagram representation after eclipse restart [message #1703149]

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>

Thanks again Maxime,

Found the problem. Looking at my .aird file my root target was:
<target xmi:type="" href="test.mo" />

My viewpoint specification model I had domain class=DocumentRoot for the root Diagram Description element. Changing this to the true root element of my schema plus adding a namespace to my schema I now get a valid target type in the .aird file and I can reopen my diagrams after restarting eclipse.

For some reason DocumentRoot is being added to my model hierarchy and is shown in the model create wizard so that's why I had used it in the design description.

Thanks so much for the help.

Rob
