Ok, I see. Maybe this is not such a good idea then.. We will see.
But in general, when structuring my code into several classes, I need to access the PeopleManager and other managers, so I need the Session. As for now I am defining a session in each class, but the only place I initiate it is in the base class. Whan calling other classes (ie forms for user settings), I pass on the session to this class. Another way of doing it would be having the Session defined as a global variabel. I am not that experienced, yet.. I appreciate any comments or advices :-)
