*** Bug 449264 has been marked as a duplicate of this bug. ***
Do you have more details about the scenario? Indeed, by analyzing the stack, I see you double-click on a representation, but just after (during the opening of the diagram), the semantic root element of the representation seems to not be in a resource of the current Session. I do not understand how it is possible. So I can not make a reproduction scenario.
That's actually quite possible when editing Ecore models. The Ecore model has a reference to "something in the EPackage registry" which is not part of any session. In the end, InterpreterRegistry.getInterpreter() should be banned from our source code as we *always* have a mean to explicit pass the current session and its interpreter instead of relying on this registry.
You're right Cédric. Here, in method DDiagramEditorImpl.hookGraphicalViewer, we can directly use getSession() method and get the corresponding interpreter.
You're right Cédric. In this method, DDiagramEditorImpl.hookGraphicalViewer(), we can directly use the interpreter of the session. Like in this gerrit: https://git.eclipse.org/r/40534
