Hi,
We've upgrade recently the project from Infragistics v16.2 to v18.2 and during testing we discovered that one functionality is not working. After long analysis I figure out that this functionality was working with older version but it got broken after update.
Unfortunately I cannot provide more specific details since creating a reproduction problem might not be simple due it involves a lot of actions.
Here is a stack trace:

Forgot to mention that this happens on treeNode Clear:
cellNode.Nodes.Clear();
