Because when i click on checkbox of tree, treeitem selected status is true. When i click again on this checkbox, status not changed (true instead false). I want to set this value independently.

I am select item2 (under debug) and watch in onEvent method of SelectTreeNode. Selected treeItem is "Item 2". After i select "Item 4", but the selected item again is "Item 2" instead "Item 4". What can i do? Because, when i use getSelectedItem() method of tree, i need in current selected item...
