Extending the ActionForm Class

• When framework receives a request, the ActionForm for the request is looked up in the mappings, and a form is either created or reused
• This form has accessors and mutators for the customer access number and pin number
• Framework uses accessors and mutators to populate the form fields from the request object
• Overrides two methods that are called by the framework:
  • reset(): called before populating the form
  • validate(): called after populating the form, and returns any validation errors
