All Implemented Interfaces:

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.
