I could be wrong about the reason for the message, especially since I've
never used Class::DBI::AsForm, but if you don't understand the
differences between class and object methods in perl you definitely need
to re-read the OO man pages.  It's very significant.

Yes, when you call Class->has_a_new() it sends a class name and when you
call $obj->has_a_new() it sends a reference to a specific object.

No, that's not going to help.
