Sure, use a construction like:
TextField c = new TextField("field");
c.add(new TypeValidator(Date.class)

Ah yes, but I'm just creating a delegate method, I don't create the
validators. They are passed to me by the person building the panel.
Now, if Java let my subclass instances, that would be sweet. I'd
prefer to not go the bytecode manipulation route, however. :)
In that case it is either the responsibility of your user (you could
help him/ her by provide factory methods for creating common validators)
or you have to use the decorator pattern. If you use the latter, and let
the user provide the key that should be used, you'll be flexible /and/
have your goal met.
