We are using Nevron Diagrams for Winforms to build graph diagrams and are having difficulties with the routing. The objects placed on the surface are groups of objects that are bound together and have a dynamic HV connector to other grouped objects.

We have two problems:
1) When we set the location of all the objects explicitly, and then ask the document to reroute, the NGroups are not routed around (This is used to allow the user to save their preferred layout).
2) When we move an object after applying an NLayerGraphLayout, and ask to reroute the line, the NGroups are not routed around.

Routing does work around groups in the initial layout of NLayeredGraphLayout.

What we see is we have connectors that run directly through the centre of an group if it's connecting to another group that is on the opposite side of the port applied to the source group.

We have been able to replicate this in the Nevron demo apps using the Group Layout within the Document Object Model examples. You can see a screenshot of this below. Also attached are examples of where the routing is not working properly within our application.

How do we route around NGroups?
