Hello there,
I am having a slight problem with my diagram editor, the source of which
I am been unable to find.
In my diagram editor, I am able to add any number of nodes ( know this
as I can see them added into the domain model file ). However, they are
all fixed to the top left-hand corner and I am unable to
select/move/remove them from the diagram editor. Inspection of the
diagram model file in a text editor shows the nodes placed at different
x,y locations with varying width height.
I was just wondering if anyone has had this problem before (I know one
has, but the cause doesn't seem the same) and how they solved it? I have
not edited any of the files in .diagram myself.
Thank you
Paul

Hello,
I'm really having a bit of a hard time trying to figure out what the
cause of the problem is/a solution; any help would *really* be
appreciated! :)
Thank you

Thank you for the response. Unfortunately, due to my somewhat limited
understanding of GMF/GEF, I'm not entirely sure where to put the code
you have provided.
First, I assumed that I would add it to either the xxxEditPart of my
nodes or of the model itself (as part of the createDefaultEditPolicies()
method). Is this the right place?
Second, I was assuming originally that this was code I was meant to add
to a createViewsAndArrangeCommand method, but not being able to find one
in any of the files in my ".diagram" project, I assumed the idea stated
previous. Again, have I got the right idea here, or am I meant to
implement this method myself ( instead of using the one defined in
org.eclipse.gmf.runtime.diagram.ui.editpolicies.DiagramDragD ropEditPolicy ).
Thank you once again for the response and any further clarification
would be greatly appreciated :)
Thank you

Hello Paul,
I had similar problems, even with a fully generated editor. Perhaps your
editor has a problem and thats why it does not place the nodes elsewhere.
Please use your debugger to see what happens. It looks like an Exception
is thrown this should be trackable.
Regards
Malte
