Hi,
I would like to know how we can generate a link with mulitple source and
target.

Can we use a invisible node betwen multiple incomings and outgoings?

Hello Patrick,

Yes, you have to "simulate" this kind of link - GMF supports only links with
one start and one end, so you can create intermediate node on diagram and
draw several links to/from it.

Have you an idea how to program this solution with the runtime of gmf?

Hello Patrick,

I think you can add one more node to the domain model - "link center" one;
add NodeMapping for this node; add LinkMappings describing links to/from
this node to actual link destinations and generate diagram code. Then you
can try tuning this diagram like: implement proper viewmapping for this "intermadiate"
node and all the links. If you fill this solution is ok for you then you
can follow it and generate all the code by GMF. In other cases you can modify
GMF-generated code to support these links in a different way.

In my case I can not modify the model domain. This model domain is the UML.

Well... rather complex domain. ;-)
I think you can reuse existing unl2tools project with their diagrams then.
