Redirect from phaselistener does not work as soon as the Ajax object is waiting for response, but not the browser itself. So, using custom A4J.AJAX.onExpired is a right way to go. Did you try it or just heard about it?
I have not really played with it, can i just override the method ie.
in the head element of my xhtml?
Was wondering if you could post up some example code? I'm pretty sure i;m not on the right track,
your code look good. Do you have a problem with it?
