      Parameters:
      field - the field which is currently being rendered
      message - formatted validation message, either from validation messages, or from an override
      writer - markup writer, allowing additional attributes to be written into the active element

      public T parseClient(Field field, String clientValue, String message) throws ValidationException
      Description copied from interface: Translator
      Converts a submitted request value into an appropriate server side value.
      Parameters:
      field - for which a value is being parsed

      Returns:
      equivalent server-side value (possibly null)
      Throws:
