reordering children in compartment with DnD [message #211466]

I followed the GMF recipe (http://wiki.eclipse.org/GMF/Recipes) for
"HowTo reorder children in a GMF compartment with Drag & Drop" in Europa
it worked very well. When I upgraded my editor to Ganymede (GMF 2.1.1),
there is a problem. On opening the editor, it goes into an infinite
loop, rendering the diagram. Does anybody know what needs to be changed
to get this to work correctly in GMF 2.1.1?

I suspect that you will need 2 or more, to see the pattern of what is
happening, it appears to be continually redoing the layout.

When I changed from a FlowLayout to a GridLayout, it works correctly.

Hello John,

Sorry, I can not realize the reason of the loop from these traces. I suggest
you debugging this code to see the reason (e.g. by lacing a break point into
ContainerProxy2EditPart$ContainerConnectionFigure(Figure).re validate()).

In addition you can try guessing about the reason of this looping by comparing
the code with Flow and Grid layouts.
