Moving node with keyboard (arrows) is other object instance

I found a little bit confusing situation. I created a custom derivation from the class node:

Now I listen to the event SfDiagramComponent.PositionChanged and log the the guids in console.

The following can be observed here:

  •     There are generated multiple instances for one object (I suspect for undo/redo). This is not a problem
  • If I move a node with the mouse, the first original node is also be updated

  • Now move the same node with the keys (arrows) on the keyboard

You can see, if you move the node with the keyboard the GUID '3dddbece-f3bd-4143-b706-b77643bf95b6' does not appear. But on mouse move it appears.

I use the HTML-Content in the nodes and I need the parent node instance to do some operations. Everything is working fine with the mouse but on keyboard move, it's not working any more...


Because of this, the  properties OffsetX and OffsetY have not the correct values in the diagram collection, which is used to save the diagram.
