I need to access the EObject that corresponds to an EObjectNode in the outline view. More specifically, I'm creating an action handler executed when the user right-clicks on an outline node. In the handler I have access to the EObjectNode, but I need the actual EObject used to create it. How can I navigate from the EObjectNode to the EObject?

Thanks. I see that EObjectNode has getEObjectURI and getEObject(Resource). But what I don't understand is this: if the user is seeing the outline it's because the model is in memory, so why go through the URI or the Resource? Why doesn't EObjectNode have a direct reference to the EObject in memory?

I mean navigate programmatically, in the sense that I need to obtain the EObject instance that was used to create the EObjectNode in the outline view.
