Ни BindingResult, ни простой целевой объект для имени компонента не доступны в качестве атрибута запроса при попытке загрузить модальный элемент начальной загрузки

В моем JSP я пытаюсь загрузить модальный загрузчик, чтобы сохранить и отредактировать объекты с соответствующими методами пружинного контроллера и атрибутами модели. Но когда я добавляю этот модал, я получаю следующие ошибки. Когда вкладки меняются, следующий запрос передается контроллеру пружины, который затем передает модальный атрибут в представление и, если это так, показывается соответствующий модал. 

http://localhost:8080/admin/setting/systemRole/load

Ошибка в журнале tomcat: 

DEBUG org.springframework.web.servlet.DispatcherServlet - Could not complete request
org.apache.jasper.JasperException: An exception occurred processing JSP page /WEB-INF/jsp/settings.jsp at line 181

178:                 <form:form method="post" modelAttribute="user" action="save">
179:                     <div class="form-group">
180:                         <label class="col-form-label">User Name</label>
181:                         <form:input type="text" required="required" class="form-control" path="username"/>
182:                         <h6 class="fieldError"><form:errors path="username"/></h6>
183:                     </div>
184:                     <div class="form-group">

Но он отлично работает для следующего запроса, когда я переключаю вкладку на пользователей. 

http://localhost:8080/admin/setting/systemUser/load

Когда я удаляю модальный код из кода, остальные части интерфейса работают нормально.
