public class InvalidValues extends Object
For example '42A' cannot be converted to an Integer. But temporarily it should be stored in an Integer field because it's entered by the user or was imported from an invalid source.
Invalid values cannot be persisted. They are only temporary objects in the vm.
The form class converts the String in an InvalidValues object. So the value can be stored in the Integer field. All validators should check for invalid values when validating. And when a form field displays a value it should check with the 'isInvalid' method if the value represents an invalid value.
