Subject Re: Validator Framework Questions

I think it is necessary to include a input property in the action element,
so if the data is invalid the controller can recall the form file (or
tiles action).

      <action
          path="/nameOfAction"
          name="nameOfForm"
          type="package.package.class"
          validate="true"
          input="/file.jsp OR .tiles.action" >
          <forward name="key" path="file.jsp OR .tiles.action"/>
      </action>
