I have this bug with the latest nevron that I can constantly reproduce in separate project.

1. Create a tree diagram in the nevron control using the NTreeDataSourceImporter and the NBasicShapesFactory using the table shape
2. After the tree is drawn, wait for a few seconds and change the text of the root node.
3. Weird behavior: The root node gets deattached from the tree which prevents the collapsing decorator to work, and if you drag the node it shows that it is not connected any more.

I have a sample project that shows the bug and is attached to this topic.

Any ideas?
