Hi,

I want to store a DiagramNodeList of ShapeNodes seperately to the Nodes in the Diagram. Both lists should contain the same nodes (reference equal). Sadly I cannot have the same ShapeNode in both lists, because if I assign the ShapeNode to the list, it is deleted in the Diagram and vice versa.
I also tried it with a List<ShapeNode> but the result was the same.

 foreach (DiagramNode node in diagramNodeList)
                {
                    node.Id = shapeEntry.Key;
                    saveDiagram.Nodes.Add(node); //here the node gets removed from diagramNodeList
                }
 

As a result of the code above, an exception is thrown, because the origin list is modified.

I also think that in a previous build, this problem did not occur but I am not totally sure about that.

Best regards,

Cyrinael
