I don't know if it's common practice to send thank you's in a mailing list, but
screw it. Thanks! I'm pretty sure I'll be using much more of Tapestry in the
future.

Exactly the same. The actual name of the session attribute (which you
should consider completely irrelevant) is based on the fully-qualified
class name. The field name is ignored.

Yep. Or just create another class, for example, UserState, with two
different fields, loggedInUser and buddy, and don't have an User in the
@SessionState directly, so you have a single place for looking for the
current logged in user.
I've been working with Tapestry 5 since the first alphas. @SessionState
works exactly in the same way since then, almost 5 years ago. I've *never*
needed two different instances of the same class in the session.
