O$ - DAM issue - differences between dev and runtime

Hey Nick,

I knew that one :) But I still don't get the internal reasoning behind
the difference of do default and do inherited (and their notational
counterparts). In the end you are always overriding a method and calling
the inherited version, even if in some cases that inherited version is
an Omnis internal one. With the print I kinda follow the reasoning as
Omnis does not see the method as being inherited from the internal one
as the internal logic isn't really a method you are overriding.

But with the table classes $insert, $update and $delete are methods of
the internal table class which are supposed to be in no way different as
where you are subclassing an external object. Or maybe I am mixing up V3
Dams and table classes :D
