The way we did it was as follows (where processAction is an
actionListener method):
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();
...
}
...
}

Subject: Re: node selected in n-level tree
Have you seen the recent discussion ("tree2 summit") on myfaces-dev
list? We are considering moving this functionality to a new TreeModel
interface so the user could control node expansion. The same could be
said for node selection.
