Hi.
I've the same problem.
It's possible to "freeze" the position of a node, during layout
updating, using ContraintAdapter ...
it's a little bit of code:
@Override
public void populateConstraint(Object object, LayoutConstraint constraint) {
if (constraint instanceof BasicEntityConstraint) {
BasicEntityConstraint basicEntityConstraint = (BasicEntityConstraint)
constraint;
GraphNode graphnode = (GraphNode) object;
Object data = graphnode.getData();
basicEntityConstraint.hasPreferredLocation =
!getApplyLayoutSet().contains(data);
}
}
where "!getApplyLayoutSet().contains(data);" it's my "freeze/not freeze"
condition.
Well ...
How can catch the "move node" event?? ...
The problem is same as the just signaled bug:

Cheers
Marco
