yes, a page instance is only accessed by 1 thread per request per user.
so that it is completely clear: (in my eyes)
yes, a page instance is only accessed by 1 thread per request per user at the same time.
because you could have more then 1 request for the user that will normally be handled by more then one thread (at the same time)
But we sync on the session so that this doesn't happen there can stil be 2 request that are handled by 2 threads
but the handling of those threads in wicket is serialized so that the page is only access with one thread at the same time..

What do you mean?
per request there is only 1 thread. or are you saying that during a request multiple threads are
used? (this is contradicting with the servlet spec in fact, so I guess I am not reading correctly).
