Hi,
I have the following situation:

+-----+              +------+
|  A  |              |   C  |
+-----+              +------+
  <>                    <>
  |                     |
  |                     |    
+-----+         0..* +------+
|  B  |------------> |   D  |
+-----+              +------+

I have two diagram editors: one for A, where I can create nodes of B and a diagram editor for C, where I can create nodes of D.

Now I want to draw a line from B to D, but D is not a top node reference in the diagram editor because D is contained by C. However, I can select an instance of D in B's property view. That works, but I want to use a connection line.

How would you solve this problem ?!
The nicest would be to have sth. like a dummy node of D in A's diagram editor, is this possible ?!

thanks

Hi,

I have seen a tutorial for this a while ago. Unfortunately I cannot find it anymore. There is a way to have nodes from one diagram in another which link between the two. As far as I know it has to do something with shared editing domains. You can find information on this here: http://wiki.eclipse.org/Graphical_Modeling_Framework/Tips#Sharing_single_EditingDomain_instance_across_several_diagrams I hope this helps a bit further.

that is actually too bad that you can't find the tutorial. My diagram editor already implements the shared editing domain.

Does anyone else knows about that tutorial ?!

I found a thread which had a solution,
it links to the following thread:

http://dev.eclipse.org/newslists/news.eclipse.modeling.gmf/m sg09370.html

But the link is dead. Is there a way to access the thread anyhow ?!
