Hi all,
I'm currently upgrading a project from EMF 2.3 to 2.5. The old model files
contain references like this:
<elements xsi:type="m:Foo" alias="MY_FOO" />
<elements xsi:type="m:Bar" associatedFoo="MY_FOO" />
That is, in my Ecore model, the attribute alias of class Foo has ID set to
true, and all references are serialized using this attribute. I don't recall
changing anything to get this behaviour, but this might not mean much - I
haven't had to touch this model in almost two years.
After upgrading - without changing either the ecore or the genmodel, but after
regenerating of course - I can no longer open the old models. The error
message is UnresolvedReferenceException: Unresolved Reference 'MY_FOO'. When I
create a new model, I can see that the serialization has changed like this:
<elements xsi:type="m:Foo" alias="MY_FOO" xmi:id="_xxxxx" />
<elements xsi:type="m:Bar" associatedFoo="_xxxxx" xmi:id="_yyyyy" />
Is it possible to get the old behaviour back? I should mention that I
use a customized editor that I can't regenerate - perhaps I'll have to change
something there?
Thanks
Volker

Never mind. GMF didn't recognize its own old extensions and added new
extensions in addition to the existing ones. Somewhere along this way, EMF
decided to bail out. Once I cleaned up the mess, I was able to open my old
model files again.
