Groups of groups picking issues

[jhshen]

Thanks for reporting the nested group manually resizing problem. The suggested code may not be ideal, since pickedElement is usually used for top-level element, and we have separate fields in the hit record for sub-item/part selection. Some of our clients have custom highlighting for the active group hierarchical selection path so it is better to keep the pickedElement for the top-level elements.

I have submitted a fix for Ron to review. It should be checked into GitHub by tomorrow.

Thanks for the quick turnaround. The fix seems to work in most cases, but there is still an issue. I wish to have certain nodes not have the ability to be dragged (they are always fixed children of a group) so I did some testing by modifying the code in AllowDragging. By doing this, it is possible to have a node selected (so CanDragging returns true), but then have AllowDragging return false. This leads to an exception (System.IndexOutOfRangeException) because it is then possible for m_draggingNodes to be zero. It is odd that even though the check m_draggingNodes.Length fails (length of 0), the exception still happens, which I think would only be the case if m_draggingNodes[0] were called.

Thanks for your detailed explanation. I will look into this soon.

My latest check-in should fix the IndexOutOfRangeException.
