Hi,
I have two ecore models, each live in its own project and the first has references to the second. I have both projects
in my workspace. I also have an older version of the plugins that both projects represent installed in my IDE. They are
however not present in my target platform.
The references from my first ecore model to the second starts with "platform:/plugin/..." and my problem seems related
to how this URL is resolved. When I open the model using the reflective ecore model editor, it loads a resource
representing the latest version of the second my model (the one in my workspace). So far so good.
Now I open the corresponding ecorediag file with the Ecore Diagram Editor (the ecorediag file has the exact same
"platform/:plugin..." references). For some reason this editor loads the resource from the plugin installed in my IDE. I
haven't been able to figure out why. Loading from the target platform could be OK if the versions were equal (I can
understand how that could become an ambiguity), but from the IDE? That's just plain wrong, isn't it?
What kind of behavior should I expect here and how can I make sure that the correct model is loaded at all times?
Regards,
Thomas Hallgren

EMF doesn't yet support references into the target platform.

So when you created the model, you referenced the Ecore in the installed
IDE...

The Sample Ecore Editor?

Yes, it does redirects in the platform:/plugin case to find the version
if the workspace when it's present.

It probably doesn't have the little bit of magic that's in the Sample
Ecore Editor.
public void createModel()
{
*editingDomain.getResourceSet().getURIConverter().getURIMap( ).putAll(EcorePlugin.computePlatformURIMap());*

Less than ideal. :-P
There's a bugzilla open to support things in the target platform, but
the resource to make that work seems never to be available.

Better to reference the platform:/resource version then. In that case,
references will be relative, i.e., ../../<project>/model/Whatever.ecore
