HI! I have child edit parts which I would like to have non-moveable. My
edit policy for the parent implements createChildEditPolicy(EditPart) to
return the NonResizableEditPolicy for which setDragAllowed(false) has
been invoked. I selected the object and when I try to move it, I get the
exception posted below. I find it odd that that dragging is being handle
when I have explicitly asked that it not be.
Any suggestions as to what could be the problem?
