Damn Heissenbugs ;) I can only suggest to try what usually do to
create my validators, that is, overriding to_python and calling super
cooperatively before my own validation:
def to_python(self, value, state=None):
value = super(MyValidator, self).to_python(value, state)
.....
Not sure if it's the best approach but "Works For Me ®" :)
