Hi,
I have a question. I want to create an GMF-editor which consists of nodes and links. The nodes should have an additional information which is an attribute in another package. Is it possible to join the node and the attribute while they are in different packages?
Thanks in advance
Teresa

It sounds like all you need is an EReference in one EClass whose eType
is something other EClass...

I imagine there should be a connection in the model itself, i.e., some
type of EReference to relate the two things.
