If we want to Extend the behavior we have to execute "DoDefault()" every time in every child's Event/Method if we want the parent's Event/Method to fire, which I think is really a pain in the a##.

I tend to agree with the others who have said that the way it is works pretty well, and to change the methodology would break so much code it wouldn't be worth it (unless of course enough other things broke enough code as well, but I digress).

However, I also rather prefer coding the superclasses so I don't have to use DoDefault() very much. e.g., a typical Save() method.
The superclass Save() contains all the necessary code to save any data, w/o needing any coding at the child level.
The only child specific code needed would be to check required fields and to validate data using other business rules.
In this case, the superclass would have the CheckRequiredFields() and IsValid() methods (as an interface), with no default code except to maybe return a value indicating success (RETURN .T. or RETURN 0, etc.).
The CheckRequiredFields() and IsValid() methods are overwritten by the child level. In none of these methods would a DoDefault() be required in the child.
