Re: [JStateMachine-users] Session values

[Robson M. <rmi...@so...>]

I solved it creating a ModelManager, which hold associations between the
session id and a hashtable of session values. This way, there is no
dependence with a servlet implementation of UserSession.

Anyway, I also found that there is no checking of user access to a state
which wasn't visitated... I'm working on this now.
