Yes I am getting action events from h:commandLinks. Could you please give me rough idea how I can sub class the tree2 component and put an action listener for "+" and "-" images also?

The tree2 component doesn't support the actionListener attribute. You can subclass the tree2 component add the functionality. ----- Original Message ----- From: "Mihir Solanki" <[EMAIL PROTECTED]> To: "'MyFaces Discussion'" <[email protected]>; "'Sean Schofield'" <[EMAIL PROTECTED]> Sent: Monday, April 11, 2005 5:42 AM Subject: RE: selectionlistener for tree2 Sean, I have created tree2 and as per this email thread, I am getting action events in my bean whenever I click on either "images" or "description text". But the only problem is when I click on "+" or "-" images I and not getting the action events as these images are (I guess) put bye the tree2 component... So how do I get action events on "+" and"-" images for the consistence behavior...

If you want the tree to keep track of your selected nodes for you then you *must* use: actionListener="#{t.setNodeSelected}" But if you want to handle things yourself, then there is nothing wrong with what you are trying to do. sean On Mon, 28 Mar 2005 18:50:35 +0100, Roger Lee, NOTiFY <[EMAIL PROTECTED]> wrote: > Sean, > > Could you clarify which Listener I should use for tree2.
