tree2 setNodeSelected()
Hi, the great myfaces users and devs,
I really need some help regarding the tree2.
I know I can use t.setNodeSelected() to select the tree node. And rendering the tree node based on the selection.
But how to deselect the tree node?
How to refresh the tree to make all the nodes unselected?
I cannot do something like below, coz the deselection event is not triggered by clicking on the tree. Anyone can help me?
public void processAction(ActionEvent event) throws
AbortProcessingException {
UIComponent component = (UIComponent) event.getSource();
while (!(component != null && component instanceof
HtmlTree)) {
component = component.getParent();
}
if (component != null) {
HtmlTree tree = (HtmlTree) component;
TestNode node = (TestNode) tree.getNode();
...
}
...
}

Hi Sean,
I appreciate your time to reply my email.
Here is my situation,
I click on one node of the tree, make it highlighted (or say selected), then
on another frame, I do some process based on that node's identity, and then
go back to the tree.
At that moment, I want to see the original tree that no node is selected.
Is that possible?
To make it clear, I attached a screenshot of my page.

Its been a while since I worked on tree2 but I'm planning to get back
to it soon now that the maven stuff is mostly finished.
You said all of the nodes unselected but only one node can be selected
at a time. Did you mean collapsed instead? If you really did mean
unselected, unfortunately the selected status is only easily
accessible through the action event (which knows to apply itself to
the correct node.)
A while back we introduced TreeState and TreeModel interfaces.
Unfortunately that only helps you with expand/collapse. I need to get
back to MYFACES-911 which will add a lot of new flexability to tree2.
Unfortunately the patch is now broken because of the maven reorg so I
need to rework it.
