All right, so as scott said the SessionAccessCounter
is incremented when browser B is opened using ctrl-n,
meaning that when I go back to browser A and submit
the form which still contains the old value for
_session_access_counter, the test in
TemplateSessionValidator:
if
(data.getParameters().getInt("_session_access_counter")
<
(((Integer)
data.getUser().getTemp("_session_access_counter"))
.intValue() - 1))
evaluates to true so the Action is not performed. This
is a massive bug for my app since people are often in
the middle of filling out a form, then realize they
need to look elsewhere on the site for more info.
(btw, i'm not sure if this happens on all browsers,
but it does in ie, which everyone here uses)
Does this 'work as designed' or is this a bug? I
obviously need to patch it for my app, does anyone
else need this?
