I like a node with no connections to be say red boarded BUT once a
connection is made from it I would like it to change to grey.
Any help would be great (even if its - stu this is not possible),

Thought I'd post the code that I used in teh end to solve this issue. Maybe
it might help someone else:-
The code is implemented in the <NodeYou WishToBeDynamic>EditPart in the
diagram project. It overrides a super class method.
protected void refreshSourceConnections() {
super.refreshSourceConnections();
if
(((ActionNodeImpl)((NodeImpl)getModel()).getElement()).getWh ereNextConnection()==null)
{
getContentPane().setForegroundColor(new Color(null, 255, 150, 150));
} else {
getContentPane().setForegroundColor(null);
}
}
