Re: Page Map Is Locked, Can't Switch Pages When A Transaction Is
Ongoing
I'd suggest running the transaction in the background (separate
thread) and using an AjaxStoppableSelfUpdatingTimer to periodically
check if the thread was finished and only do the redirect after
finishing. This way, the pagemap remains unlocked.

Re: Page Map Is Locked, Can't Switch Pages When A Transaction Is
Ongoing
Posted by Ernesto Reinaldo Barreiro <re...@gmail.com>.
I would use timer as comet introduces additional dependencies...
I have used comet-push for other things but not via wicket-stuff project.
Thus, I can't offer any help.

Re: Page Map Is Locked, Can't Switch Pages When A Transaction Is

if i can't do this, is there anyway that i could at least increase the
timeout of the pagemap to greater than 1 minute?
1 minute would be too little i guess

Why not follow the Jeroen's suggestion instead of trying to trick framework
internals?

I'd suggest adapting your application to use Wicket properly instead
of the other way around. I'm not a Wicket Dev but I'm pretty sure that
desynchronizing page map access will cause more problems than it
solves.
Your problem is that Page A displays data which can take a lot of time
to gather due to polling an external system. So use this scenario.
1) Upon load, Page A starts a thread that fetches the information, and
displays a placeholder (a "loading" image or something like that).
Once the page is loaded your thread will be running and the pagemap
unlocked.
2) Use Ajax polling (in the way I suggested) to check if the thread
has finished. This will not lock the pagemap so you are free to
navigate the site. Once the thread is finished, you can replace the
placeholder from step 1 with the actual panel
Alternatively, you could use a push solution (e.g. wicketstuff-push)
to automatically publish the data upon thread completion (or append it
as the data comes in).

hi,
i believe this is due to the fact that wicket has synchronized page maps for
access.
do you think it is safe to remove it?
what are the precautions when removing synchronized for wicket page maps?
Is there a setting that I could use to disable this?
Thanks A Lot
