I have an application that users fill out and can enter a long winded response to some questions. My problem was that there session would time out and when they clicked next they would be sent to a Seam Debug page. I fixed that by changing the conversation timeout to be an hour and the web session also to be an hour. (wow so not the right thing to do).
What I'd like to do is have an A4J:POLL hit something on the backend that would keep both the sessions alive ala google docs.
What's the best way to do this? Do I use a4j:keepalive or a4j:poll or is there a better pattern to do this.
