best thing todo currently is to have that -1 check in the pagemap and make your own version of wicket 1.2

I guess to fix it for the AccessStackPageMap (2.0 name) is to have ajax request always check the active
page first and only do its job when it is the right one. But this is i think pretty tricky to do because we need
to synchronize around the right places again.

in trunk (2.0) this is already fixed in the default setting because we refactored the pagemap
and have now a different default pagemap and httpsessionstore.

Hi,

It is very important for us to get this fixed, preferably for 1.2.
If any wicket committer is willing to help us, we will pay
for the work (please contact me directly by e-mail for this).

problem is, not every ajax behavior uses version -1. i guess we need to have
the ability to tag a request as process-only-if-page-is-active
