Ok, thanks for the hint, but the operations I make usually only take up
to ~1min, so I guess this won't be an issue in my case. But you are
right, one has to assure that the polling will stop upon completion of
the background task.

You have to watch session expiration. This type of polling, without end,
will keep sessions alive indefinitely.
I don’t have a cut and paste code, but look at AbstractAjaxTimerBehavior.

AjaxButton.onSubmit()?
Hi Ernesto,
this sounds like a viable solution, I'd be glad if you could provide me
with some more details (e.g. code samples, if available).

Hi Tom,
What I do, for instance, when exporting files to PDF, Excel, etc, is start
the process on a background thread, block the screen so that users can
only
wait or stop the process, and use an AJAX timer to get back to the server
every few seconds to monitor the progress and display it as progress-bar.
This seems to work fine for me but might not be the most efficient
solution... I can give you more details if you want.
Best,
Ernesto

Thanks for all the hints so far, they are really helpful .... but ;)
Well, I don't want to have busy indicators on different components, I'm
looking for a way to display status messages (like eg with jGrowl) during
the long-running process (triggered by AjaxButton). I guess the only way
to
achieve this is with a solution as stated by Nishant (involving some kind
of
JS polling) ...
