Use External EMF Resource [message #1760170]

Hi,

I'm using an external, non-containment, EMF Resource inside my actual Diagram Model.

When the diagram gets initilaized I add this external resource with an

AddSemanticResourceCommand

to the session of my diagram Model.

However I get the following message.

Impossible to find an interpreter - Could not find a session for model element :
!STACK 0
java.lang.RuntimeException

After I close and reopen my project everything is working fine. I look up the Bugzillas known for that issues but they didn't get me anywhere.

How can I properly use external EMF Resources inside my diagram?

Thanks in advance,
Matt

It seems the Resource gets copied within the AddSemanticResourceCommand process.
I solved my problem by looking up the URI afterwards like:

for (Resource resource : session.getSemanticResources()) {
			if (resource.getURI().equals(externalResource.getURI())) {
			    ....

			    break;
			}
		    }

and use this resource.

But it's more of a hack than a clean solution...
Any Recommendations?
