I think it's about writing clean and maintainable code. For other developers reading back your code it makes more sense if you add your validation errors in the ValidateForm event and to perform some (database?) action in the success handler. The ValidateForm event is where validation errors are added and some of them are automatically taken care of for you by the Tapestry validator mechanism. If you don't want to add more than one error-message, you can easily check if the field is in error already. Sometimes it also makes sense to add mutiple errors per field since you're telling the user immediately what (s)he's doing wrong instead of having them re-submit again only to find yet another validation error on the same field. regards, Onno
