Pagemap help
Hi,
I have a page that has a AbstractDefaultAjaxBehavior which adds a new panel
in the ajax request. This new panel can be a long running process to
generate some data. I'm find this is locking the page map so other requests
on that page get locked.
How could I get around this aside from re-enginering the panel to
poll/notify? Is is possible to create a new page map? I looked at the
inline frame code but it doesn't seem to look any different regarding the
page map. I'd really like to avoid the polling solution if possible for
various reasons.
thanks

Well, you can create a Wicket resource for the updates to avoid a
pagemap lock, but it is essentially the price we pay for having a
singe-threaded access to the component hierarchy.
You can also create a servlet, but both options will block a thread on
your server waiting for the processing to finish if you don't want
polling. That is effectively a kill switch for your application (some
users will double, triple or N-click links if things are not going
fast enough).

Hi Martijn,
are you basically saving that with wicket there is no way I can not avoid
the pagemap locking for a given ajax or iframe request when needed?
BTW web sockets aren't supported in IE8.

you probably should look into websockets if you don't want polling.
