Hey all,
I'm trying to programmatically move an element from one location to
another in my diagram.
My first approach was to create a GEF command from a
ChangeBoundsRequest. This did, in fact, move the element (visually) but
the move isn't recognized in the file if I immediately save the diagram.
Thanks,
Jerry

Thanks for replying Mohammed.
The problem with that method is that it simply creates commands from
ChangeBoundsRequests. When I do that, the change works on my diagram,
but when I save it, it goes away. When I reopen the diagram the element
displays in the top left corner of the diagram.
Any more ideas?
Jerry

Hey all,
The whole problem was that my element wasn't persisted to begin with.
Thanks, Mohammed for your reply to my problem as well as your
explanation of view persistence on the "Problems persisting custom
border" thread.
