Database validation in Simpleformcontroller

[Mark Reyes]

Hi All,

For simple checking if a command bean is empty/whitespace, I can used the validator for these and add error on the bindexception object but with db validation logic
you should let your controller do it.

What about if I perform some database validation logic on the simpleformcontroller:

protected ModelAndView onSubmit(HttpServletRequest request,
			HttpServletResponse response, Object command, BindException errors){
	//DB Validation logic
	if (fail){
		errors.rejectValue("Invalid", "Invalid", "", "Invalid")
		showForm(request, errors, getFormView());
	}	
}

Will this still be valid?
