I have a Diagram control bound to GraphLinkModel.
After I change the model by adding or removing links sometime (I can’t figure out exactly when) the link that is added is not visible on the diagram.
After I move one of the nodes connected to the link the link appear.
When I add link between nodes that already have link between them I can see the exists link band a bit which means (I think) the link routes are calculated and updated.
I do all my model manipulation inside transaction, and I also call the PerformLayout on the Diagram control after the transaction finishes.
What can I be doing wrong?
