  1. If the validate is true than the form's validate() method is called. There's no need
to call it explicitly and because of ValidatorForm doing all the validation automatically,
all that is required for code is a call in your form's submit() method to super.validate().
If you are using DynaValidatorForm, then you will not have program any form beans at all.
