Re: Not Using Correct Session Sub Class?

I'm almost certain that won't be good!  :-P  WO won't take well to using a
WOSession subclass in place of a WOApplication one!  I don't recall there
being parameter for the session class.

In any case that would not be the problem. He wants to use Session as the
class, but it was not seeing what was declared in the superclass of
Session.  That almost certainly means some sort of build error happened and
Application started up using WOSession directly.

vexCode...
