Я получаю эту ошибку здесь
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'userForm' available as request attribute
root cause
java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'userForm' available as request attribute
Я старался, чтобы найти ошибку, но не может получить его, так как я новичок в весенний период. Что может быть возможной причиной здесь?
