Tree selection

[Samyem Tuladhar]

In the stock Tree widget, if there is a selection made on a node and if the parent is closed, the selection moves to the parent node. Is there a way to change this behavior not to move the selection to the parent node? This causes some issues when we have a selection listener and the act of closing the parent node invokes the selection handler even though the user did not actually change the selection. I want to keep the behavior similar to how Vaadin does with their Tree control: http://demo.vaadin.com/sampler#TreeSingleSelect
