- All Implemented Interfaces:
- FieldValidator, ShortCircuitableValidator, Validator
- Direct Known Subclasses:
- ConversionErrorFieldValidator
public abstract class RepopulateConversionErrorFieldValidatorSupport
- extends FieldValidatorSupport
An abstract base class that adds in the capability to populate the stack with
a fake parameter map when a conversion error has occurred and the 'repopulateField'
property is set to "true".
The capability of auto-repopulating the stack with a fake parameter map when
a conversion error has occurred can be done with 'repopulateField' property
set to "true".
This is typically usefull when one wants to repopulate the field with the original value
when a conversion error occurred. Eg. with a textfield that only allows an Integer
(the action class have an Integer field declared), upon conversion error, the incorrectly
entered integer (maybe a text 'one') will not appear when dispatched back. With 'repopulateField'
porperty set to true, it will, meaning the textfield will have 'one' as its value
upon conversion error.
