Thanks for your response, but what do I do in case the case of the
error page, for example? I'm not performing the transition myself in
that case (but I still need to do a rollback).
Plus, there are a lot of ways to go from page to page. It seems a
pain to add commit code to every link event handler, every button
event handler, etc, that takes the user from one page to another (plus
there's the possibility of forgetting to add it somewhere).
Therefore it would be nice if there was one place where the Wicket
framework could automatically tell the programmer, "Hey, you're going
to transition to a new page now", so that the programmer has a chance
to do any cleanup etc. That's why I was hoping there's a
"onPageTransition()" method on the application object, or something
along those lines.

Hopefully a simple problem for the group... What's the best way to

the application object receive any Wicket messages like

or anything like that?
I ask because--in my application--when the user finishes
interacting with
Page A (typing data, submitting form, typing more data, submitting
form
again) and then transitions to Page B, I need to commit or rollback
the
database transaction that holds Page A inserts/updates. This has
to happen
before the user actually sees Page B because there could be a
problem with
Page A data.
BTW, in case it matters, I'm using an object database so I probably
can't
take advantage of any Wicket extensions for Hibernate or whatnot.
Thanks for any info!
