Hi,
best thing todo currently is to have that -1 check in the pagemap and make
your own version of wicket 1.2
We already decided to put my modified version to production and
if there are no side effects from my change we can keep it for some time.
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.
You mean that if I would use 2.0 from trunk the problem would go
away ? If so, would it be possible to back-port the new pagemap
to 1.2 branch ? Not as default, but something that I could turn on from
application settings ?
Another point: when 1.2 is released, someone else might also
hit this problem so it might be necessary to implement some kind
of fix anyway (at least for us, some pages were almost unusable
because of this as other pages worked quite ok - it seems that YMMV).

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).

Subject: Re: [Wicket-user] pagemap problem with late arriving ajax request
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
