[Seaside] Displaying progress on a web page

Thanks Philippe,

I think fixing Comet is a little bit much for a relative newbie like
myself to chew on :-), but I did try the periodical updates and I got
the effect I desired. Was just wondering if there was another way to do

About the script redirecting to the next page, do you maybe have an
example of such a script? Or is there a way to stop the updates? I have
this scenario now where the update just keeps on running even after no
progress has been made on the client side.

Thank you,

Ideally you would be able to use Comet for that. It would allow you to
create events on the server and evaluate them in the client.
Unfortunately it's not there yet.

So either fix it yourself ;) or use polling (periodical). The overhead
should not be that heavy if you only have a few users and comet would
require an open http connection and periodical updates anyway.

When the progress is done, inject a script that redirects to the next

Just remember to run the periodical updates in a new Process.
