Your error message says that Neither BindingResult nor plain target object for bean name 'register' available as request attribute. If you look at your getLoginForm method, you're only populating the "login" object, not the "register" object in the model. If you want two forms on one page, I think you want one method = RequestMethod.GET method that populates the defaults for both forms. Anytime you're displaying this page, you need to make sure both form backing objects are populated.
