title: Primefaces Tree: click event on node's label when selectionMode='checkbox'
body: <p>I'm using the primefaces[3.4] showcase with tree and checkbox selection:</p>
  
  <p><a href="http://www.primefaces.org/showcase-labs/ui/treeSelectionCheckbox.jsf" rel="nofollow">http://www.primefaces.org/showcase-labs/ui/treeSelectionCheckbox.jsf</a></p>
  
  <p>Is it possible to attach a p:ajax event for click on node's label??</p>
  
  <p>I need to update a panel with children objects when user click over tree's nodes labels, not necessarily when user select them (click on checkbox).</p>
  
  <p>Thanks in advance.</p>
