I do have a simular problem with clientBehavor and primefaces ajax tag. When a clientBehavor is defined in the composite component and in the view the composite component is used with primefaces ajax then the clientBehavior is not added to the component but will added with faclet ajax. Did anyone face this ? Is there anything to be aware of maybe naming convention of the clienBehavior name ? I tried this with an trivial example with nothing defined but clientBehavior and i cannot get this work. We need the callback parameter provided by primefaces ajax tag. Is that an myfaces issue or primefaces related ?

--- Begin Message ---Hi leonardo, this example works: You can try the alternate syntax using "targets". For example: <composite:interface> <composite:attribute name="action" targets="testComponent"/> </composite:interface> <composite:implementation> <h:commandButton id="testComponent" value="Press Me"/> </composite:implementation> but what about whit this: <composite:interface> <composite:attribute name="action" targets="testComponent"/> <composite:attribute name="action2" targets="testComponent2"/> </composite:interface> <composite:implementation> <h:commandButton id="testComponent" value="Press Me"/> <h:commandButton id="testComponent2" value="Press Me 2"/> </composite:implementation> Im triying to use the the action attribute <mycomp:test action="#{bean.myaction}" action2="#{bean.myaction2}"> </mycomp:test> this doesnt work (myaction2 never been invoke) i guess because the name of attribute is action2 an not action, but i already use action attribute for my first button, how can i resolve this? I want to have 2 buttons in my composite component, then my 2 buttons can have action method (using the attributes). Thanks 2012/6/29 Rafael Pestano <[email protected]>: > you're welcome.
