János Cserép updated WICKET-311:
--------------------------------
In RequestCycle I found:
// clear the used pagemap for this thread,
// maybe we can move this a few lines above to have a but more
// concurrency (session.update)
try
{
session.requestDetached();
}
The other thread is blocked exactly a few lines above... So I'm starting to
have a strong feeling that this indeed is a bug...
> race condition between
> wicket.session.pagemap.LeastRecentlyAccessedEvictionStrategy and
> Session.getPage()
