I have a treeview where there is only one node at the top of the tree with several child nodes -- some having child nodes -- some not. All open / close indicators are as expected EXCEPT the very top one which even though the node is open it show a '+' sign rather than a '-' sign which is the normal display for an open node. Also clicking this top node's '+' closes the whole list AND changes the indicator to a '-' sign. Again, not what you would expect.
Any ideas?
