I created a TreeView and added some items, click on an item would change its parent's children sequence.

A test is attached:

1) start the test and see a TreeView
2) click on the item child2-0, this should result to move child2-2 to the place of the child2-0's place (done by the listener), but no change on the TreeView
3) close/open the root item, the item child2-2 is moved correctly.
