THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
...
In this example, when firstAndLast() is executed, the fields firstName and lastName will be validated. When middle() is executed, only middleName will be validated. When a method is annotated with the Profiles annotation, only the validations in the specified profiles will be performed. If no profile is specified for an action method, all the validations in the class will be evaluated.
