it is the same trick. he said its only turned off when only when you use
second level cache - the reason being that second level cache keeps a
complete clone of the page instead of the usual page+undo history.
lets say you open page A(0) in tab1, 0 being the version number. you click a
link, that results in A(1). then you click another link and tell it to open
in a new tab. this will result in A(2) in tab2.
so now what you have is
tab1->A(1), tab2->A(2)
now lets say you click a link in tab1. what will happen is that wicket will
apply the undo history to get the page to A(1) state, then execute the link,
which will result in A(3). this means that tab2->A(2), but A(2) is gone
because the page has been reverted. so now when you click on anything in
tab2 you will get a page expired error because it cannot get page A back to
version 2.
now with second level cache the same scenario looks like this
tab1->A. click on tab1 leads to tab1->A'. click and open in new tab leads to
tab1->A', tab2->A''
so you see, with second level cache the versions _are_ the complete state of
the page, you dont lose anything by reverting back to a version because
there is no "reverting".
so now if you click on something in tab1 your state will be
tab1->A''', tab2->A''
hope this explains it.

But isn't that the same trick as in 1.2?
Johan writes it is turned off in 1.3. He suggests that it will still work
correctly. Maybe I understood wrong.
