I pretty much always use strings.

If you have your field type set to "java.lang.Integer", then its value
will be either null of an actual number. It's possible that the
converter used by the validator will set an invalid input to new
Integer(0) just as a default value. So, for instance, if you enter "foo"
in for a number, it comes back "0", when it should have been "foo" (at
least, I would expect it to say "foo" and an error message).

IMHO, a rejected form should come back to the user in exactly the same
way it was submitted (plus error messages, of course).

Using strings for all form fields /will/ work, but I'm not entirely sure
it's necessary to make that happen. I just know that it works for me.
