Problem with associations between classes of different diagrams/packages [message #473497]

Hi

I got a UML2 Model that is distributed/spread over several diagrams/files.
Classes from one diagram have associations to classes of another diagram
(Packages).
I can not manage to show the associations between these classes in all
concerning diagrams.

Here is an example of what I'm trying to do:

Diagram D1 has the classes A
Diagram D2 has the classes X
An Assosiation a1 should connect class A and X ( A -----a1----> X),

To add the association a1 in Diagram D1 I created a shortcut of the
class X (X-shortcut) in diagram D1.
=> D1 = { A, X-shortcut }

Now I created the assosiation that connects class A and X
=> D1 = { A, X-shortcut, --a1--> }

Then I created in Diagram D2 a shortcut of class A (A-shortcut)
=> D2 = {X, A-shortcut}

How can I make association a1 appear in diagram D2?
Is this possible?

Thanks a lot for the help!
Markus

Hello Markus,

Described situation is a known GMF-problem. It's described in bugzilla #149547
'Ecore diagram editor : relationships between elements from different packages'.
The problem appears when an association is contained in different package,
that's why DiagramUpdater cannot access it. If you really want to display
all the associations, you can create shortcut to the package that contains
association (create shortcut to the package of D1 in D2 in your case). But
this is really incorrect way to solve the problem.

Best wishes,
Tatiana.
