Thanks very much Martino,
an fool fault!, but it did not know clearly so that was the method
getAcceptsNull(), seemed to me very similar to isRequired() and I supposed
that they had the same function.
In the end, i think in extend the class
org.apache.tapestry.form.validator.Required
and it work, but it´s clear now that the solution was but simple, thanks.
