Setting requires=IS_LENGTH() "killed" the IS_INT_IN_RANGE() default
validator for integers.

If you want a request.vars.something to be None, it should not exist in the
list of the sent values (meaning, it shouldn't be included as an input in
the form). In HTML there's no such thing as "Null" for an input value, you
get the closest representation of that with an empty field, that gets sent
with a value of '' . Use your own logic if you want "None" when the user
leaves out the field.
