How to attach edge to nodes group in my class extended from GraphDataModel? I can't create edge from node to nodes group directly using Open API but yFiles has same diagram http://yfiles.com/products/yfiles/doc/api/y/layout/hierarchic/HierarchicGroupLayouter.html
I have an issue with laoyter. I can explain in more details.
1. create nodes.
2. create edges
3. return nodes group for several nodes.
4. build diagram
5. You can see that group covers some nodes which were not included.
I think that diagram should not display these nodes.
