Link within a tree2 without a submit?

[Lars Hagrot]

I am using the Tomahawk tree2 component and do not want any server requests 
when the user clicks on a node. Instead I want to call a javascript method. 
 
Is it possible to declare a commandLink that does not resultat in a form submit 
but a  
href="javascript:foo(param);" ? 
 
Currently I am using a very ugly solution with   the verbatim tag in 
combination with a <a>-tag like 
 
<f:verbatim>
    <a href="javascript:foo(</f:verbatim>)<h:outputText value="#{node.id}" 
/><f:verbatim>); "></f:verbatim>
          <h:outputText value="#{myValue}" />
<f:verbatim></a></f:verbatim>
