Thanks, Janet for this clarification. This is exactly that my question was
all about: inheriting _visual_controls_
If NetDynamics reads HTML template into instance variable of myBasePageClass
then I think we can manipulate it in such a way that each descendant page
will be aware of "controls" of its ancestor. Trying to find out how to
accomplish that .
