[news.eclipse.modeling.gmf] href of elements changes when saving GMF edi

[chris <chris_42@xxxxxxx>]

Hi,

I have a metamodel A which refers to another metamodel B (here: 
UML.ecore; one of the classes of A has an EReference of type 
UML.ecore#Activity).

In addition, I have a metamodel C which contains a reference of type 
EPackage, which shall hold references to other metamodels (here: A and 
B). In addition, classes of C have a reference of type EClass which 
shall hold classes contained in the mentioned packages.

Finally, I have a GMF editor for C. When creating a diagram, I choose 
"Load resource" and load A. This then allows me to add A and B to the 
packages reference of c. I can then type my elements accordingly.

Now the problem is that GMF saves the instance of C such like this:

<type 
href="../../../plugin/org.eclipse.uml2.uml/model/UML.ecore#//ActivityNode"/>

Unfortunately, I run into problems with other code also working on 
models of type C. If I replace all occurences of the href attribute with

<type 
href="platform:/plugin/org.eclipse.uml2.uml/model/UML.ecore#//ActivityNode"/>

, my other code works fine. But working again on such a model with my 
GMF editor (and finally saving) changes everything back to the above.

I guess that my other code does not find the UML.ecore metamodel since 
it is linked in a relative way. Any way around this?

And since I'm not very comfortable with the whole resource stuff: Does 
anybody know a good link or two with information about that?

Thanks in advance,
Christian
