EObjectQuery on external ressource [message #1810995]

Hello, I'm loading an xmi file as a new Ressource. I can't use EObjectQuery on the eobjects of the ressource.
So, I tried to link the eobjects to the Sirius session like this :

// Get the resource
		Resource resource = resSet.getResource(URI.createFileURI(path), true);
		World myWorld = (World) resource.getContents().get(0);
		myWorld.eAllContents().forEachRemaining(o -> o.eAdapters().add(new SessionTransientAttachment(SessionManager.INSTANCE.getSession(self))));

self is an eobject of the current session.

Now I can use EObjectQuery but it does not work everytime, or sometimes it does not return all the expected results.
Is it the correct way to use EObjectQuery in this case ?

Thanks

Hello,

Which method from EObjectQuery do you need? Since this helper is supposed to be used on EObject loaded in the context of the Sirius session, it is not surprising to meet some issues.
If you need to link a new semantic resource to the Sirius session, you should use org.eclipse.sirius.business.api.session.Session.addSemanticResource(URI, IProgressMonitor) instead.

Regards,

Florian
