Have you taken out the Diagram.layout? That would mean each node would have to have a data binding on Node.location or GraphObject.position and have that property on each node data.
I’m just wondering what caused the node to be positioned where it is.
If you move that new node interactively, is the route of the link reasonable?
And that new “POM_Object” node isn’t a child of the “Enter Business Object Name” node, is it? It’s a parent.
