I followed that same example. Basically you need to disable the +/- generated by tomahawk and use your own. Which is what Bill does in his example. In your command link, or ajax link use t.toggleExpanded for the action and then have an actionListener call toggle(ActionEvent e) to load the children.

I think you can do so using ajax4jsf. There is an example here: http://www.jroller.com/plainoldweblog/entry/use_tomahawk_tree2_and_ajax4jsf I used this and it worked fine. When toggling the Items the method public void processToggle(ActionEvent p_event) is called and there is the possibility to dynamically build the tree data. (In the example the functions loadChildren(node); and unloadChildren(node);) Georg -----Ursprüngliche Nachricht----- Von: Wolfgang [mailto:[EMAIL PROTECTED] Gesendet: Dienstag, 15.

What I want is to execute a method which adds some more children to the tree by clicking the plus icon.... Thanks a lot!
