This is a quibble. If you want to put your functionality into your
ActionForm class, go ahead. Create an abstract ActionForm subclass that has
a takeAction() pure virtual method in it (with appropriate arguments).
Create an Action class which does nothing more than cast to your ActionForm
subclass and call takeAction(). There you go, functionality in the same
class that holds the data.
