Ahh, I found the problem. getCreateCommand(final CreateRequest request) in
my subclass of
XYLayoutEditPolicy was:
protected Command getCreateCommand(final CreateRequest request)
{
if (request.getNewObjectType() == State.class)
return new StateCreateCommand(workflow,
(State)request.getNewObject(),request.getLocation().x,
request.getLocation().y);
else if (request.getNewObjectType() == Transition.class)
return new TransitionCreateCommand(workflow,
(Transition)request.getNewObject(), request.getLocation().x,
request.getLocation().y);
else return null;
}
It took x and y directly from the request without converting them to
relative coordinates.
Now it does it like this:
protected Command getCreateCommand(final CreateRequest request)
{
Rectangle constraint = (Rectangle)getConstraintFor(request);
if (request.getNewObjectType() == State.class)
return new StateCreateCommand(workflow,
(State)request.getNewObject(),constraint.x, constraint.y);
else if (request.getNewObjectType() == Transition.class)
return new TransitionCreateCommand(workflow,
(Transition)request.getNewObject(), constraint.x, constraint.y);
else return null;
}
This works better. Thank you very much Randy!

Hey Roger and others,
Unless I read your mail, I never knew this problem was in my tool too. But
Thanks, I found it and solved it too.
But still the connections have the same problem. I have my own anchor class
which returns a location where the connection needs to be created, it takes
this position from the request (Create Request) and reconnect request when I
try moving it. The code for this is in NodeEditPoliciy for the nodepart. I
do not have a getConstraintFor() method there.
Could anybody tell me how do I handle this here?
Thanks,
Binti.
