Hi Luka, The JSF 2.0 specification only explains that when attaching a <f:setPropertyActionListener>, an ActionListener (with specific behavior) should be created and added to the nesting UIComponent (which has to implement ActionSource) with addActionListener().
>From my point of view it is not clear which is added first, the action listener from the tag attribute »actionListener« or the nested action listener(s), but I think the order is: first tag attributes, then nested tags. You can try to work around this problem using <f:actionListener /> below <f:setPropertyActionListener> instead of the tag attribute »actionListener«, so that it will be added to the UIComponent after <f:setPropertyActionListener> and thus executed after <f:setPropertyActionListener>. I hope this works for you. Regards, Jakob Korherr 2009/12/16 Luka Surija <[email protected]> > It looks like i'm not familiar with JSF as much as I've thought.
