I found that the way I implemented this (create a new session class and switching DS to this new object.SessionID) causes problems (can not access the table).

I'm wondering if there is a better way. I guess I will still need to instantiate a session based class, but I should not switch form's DS, I should instead invoke GetExpr as part of the class code. Or, possible, pass a reference of the class that invokes this session class - but this sounds a bit too complex....
