Issue

• Is there a good example on how to handle session timeouts when ajax is running requests on a timer in your screens?  We currently have a number of screens that have timer count queries running every minute (a4j:poll).  However, because of this, the user's session never times out.   

Let's say we have a poll which is refreshing a panel every 30 seconds.
Every 30 seconds it will execute an action before refreshing the panel.

Let's say due to some reason action always provide response after 45 seconds only.
So when poll starts the second refresh, response from first cycle is not received yet.

What I want to do is ignore this second refresh and don't execute the action in second cycle as response from first cycle action is not received yet.

Poll has to execute the action in third cycle as by that time response from first cycle would be received.

• For the a4j:poll component, how can we not fire the action if previous action didn't receive response yet?
