the default behavior is for a session to be temporary? that doesnt make
sense.
this maybe another reason. i have my login code (basically everything you've
seen) in an abstract BasePage class. I then call Index which extends
BasePage. would that have anything to do with anything?
thanks,
verbal

Either make the log instance it a static variable (statics don't get
serialized) or get it on the fly (every time you need it but don't
keep a reference).

Session#info and Component#info (and #error etc) are for a different
purpose. We call those things feedback messages, and they are intended
for communicating with end-users, for instance reporting validation
errors on a form submit. If you put a FeedbackPanel in your page, you
will see those messages.

Not anything that will help you. Component#isVisible can indeed be
called more than once in a request; not only when it renders, but also
for instance when behaviors query it. I guess the documentation can
use some improvement (I added a warning).
It is possible that your page is stateless and your session is
temporary (meaning that it isn't bound to e.g. the HttpSession yet,
and that you'll get a new volatile instance every request). You can
query that by calling session#isTemporary. If it is, and you want to
explicitly make the session persistent, you can call session#bind. See
the JavaDocs for details.
Maybe we shouldn't automagically mark pages as stateless... but I'll
post about that in another thread.
