Simple layout policy question [message #671273]

Hi, I've a simple? layout policy question.

When I try to move a child on top of another child the movement is blocked. No call to createChangeConstraint() is done and the icon is a stop sign.

I need to be able to drop on top of the child and copy the constraints to the other child.

Can someone enlighten me on where to look for this policy?

My models are very simple with one container and two different childs that I can create and move around. So everything works, except moving a child on top of another.

Since no one answer(but lot's of reads), can I assume it's a RTFM question? Or is this not possible with GEF?! (or hard to accomplish)

A more general follow up question: In my EditPart I try to use

getTargetEditPart(request)

to get the EditPart where I want to drop my child. But this always return null or itself?!
What is the flow for all the methods in EditPart and when/where does the TargetEditPart been registered?

I try to get the EditPart and fill the ExtendedData with the EditPart so that the command can find out the target EditPart, but with no luck?
