Re: actions that take long time

Nothing exists now but that does sound like an interesting idea and Stripe's Resolutions could make
it work really well. It would probably be an annotation on the ActionBean's event method, maybe
@DelayedAction("/your_wait_page.jsp"). When the event was going to be invoked it would spawn a new
thread to do the processing and do a forward to the wait page. The wait page could use JavaScript to
check if the processing was complete or fallback to a <meta http-equiv="refresh" content="2"> inside
of a <noscript>.
I'll have to play around with that idea!
