Migration to GMF 2.3: issue with Editpolicy and move/reparent [message #536916] Mon, 31 May 2010 09:44 Go to next message

Hi,

I'm trying to move from GMF 2.2 to GMF 2.3.
I encounter some issue with EditPolicy on move/reparent.

By now, I don't understand what it exactly happen... :s

Sometimes, the move/reparent (seems to) work(s) fine. But other times there are unexpected behavior:
- the EditPart is duplicated
- the Editpart is deleted
- sometimes it seems that only the refresh doesn't work.
- after a deletion of the child, sometimes the parent is filled with image of the child...

That is really weird. There is nothing in log. I don't know where to begin to search.
I noticed in the bug comment that there was modifcations in EditPolicy.
Is someone can explain in what consists these modifications more precisely?

Thanks by advance for any hints

Regards,

I'm looking closely to this issue and in fact on a reparent the old graphical definition is kept in diagram definition even if th enew one is created. Some changes are done in the model too and they work perfectly.

How the old graphic definition can be kept although the new one is correctly created?

Ok I found a workaround.

There is a modification between 2.2 and 2.3 in template for CanonicalEditpolicy (diagram::editpolicies::ChildContainerCanonicalEditPolicy)

Now it overrides the refreshSemantic method from CanonicalEditPolicy class. I commented this method and all works fine for me.

By now, I don't know exactly why it doesn't work. So if someone have ideas on the question, his comments are welcome Smile
