Does DocumentChanged apply to groups?

Walter -
I have a DocumentChanged event handler that works as I would expect if it is added to the top level document. However, if I do something like say, add a link between two nodes that are in a SubGraph, the event isn’t called. Am I missing something?
Thanks, Tyler

For that case the link is added to the subgraph, not to a layer as a top-level object. So there is still a GoDocument.Changed event, but the Hint is GoObject.ChangedObject and the SubHint is GoGroup.InsertedObject.
