Unfortunately thats not the way s:selectItems works - it doesn't make the var attribute available outside of itself (you would have to nest the a:support anyway). I'm not really convinced of a good arguement for changing this. I would suggest using an valueChangeListener style approach, where you get the valueChangeEvent with the altered property. I'm not sure what the magic combinations of a4j tags is I'm afraid :( View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4056352#...
