Link route is not permanent

I create my link in order to be able to set the route :

My issu is that my new route isn’t permanent, indeed, if I add something in my node on simply move it, my link takes its previous route… As you can see here :

What should I do to avoid that? I saw your state chart sample which behaviour seems to be what I want but I can’t find what’s the property I have to set… :$

When moving a node, the routes of all reflexive links shouldn’t be recalculated but just moved along with the node. That’s the default behavior which you see in the StateChart sample.

But if the node changes size, the route must be recomputed. That will normally result in the behavior that you have shown in your screenshots above. Perhaps you want to set the Route.Curviness?
