Hello everybody!
I am quite a newbie in GMF, but here is also something done by myself. I have succesfully created ecore model and mapped everything into diagram. I have made some code adjustments. But now I have reached a problem.
In my ecore model I have two nodes that are connected by single association and also by link (class, mapped as a link into diagram), so that you have two possibilities to model this connection - by combo box in node properties or by a visual link. What I am trying to do is to sychnronize both of them. I have managed lot of this but now I am not able to programatically create and delete this visual link. I know that I should use Commands, EditPolicies and Requests, but simply it doesnt work. I can delete eobject representing link by EcoreUtil.delete, but as reaction for this I cant delete the visual representation. How to acomplish this? Am I wrong when trying to delete it in EditPart by requests and commands?
Thanks in advance for any kind of help, Ondra
