Actually, I only cast the attribute key to a String.  The
HttpSession.setAttribute() method only allows a String for the key, so I
figured it wasn't a problem (please feel free to correct me if I am
wrong).  The FormData class keeps the name/value pair as String/Object
so that a validator, converter or storer which is application specific
can do whatever it needs with the value object.  The default validators
tend to convert the value to a String using the toString() method.

Sounds good.
