Both the values entered by the user and validation messages are stored in an Errors object. You can use SpringBindingActionForm to: 1. expose the error messages from the Errors object to ActionMessages. 2. To expose the values entered by the user from the underlying Errors object, which of course contains both valid and invalid input (the SpringBindingActionForm extends ActionForm and it provides a subclass of org.apache.commons.beanutils.PropertyUtilsBean) See the API: http://www.springframework.org/docs/api/org/springframework/web/struts/SpringBindingActionForm.html ... or the code: http://cvs.sourceforge.net/viewcvs.py/springframework/spring/src/org/springframework/web/struts/SpringBindingActionForm.java?view=markup Craig Tamas
