When trying to access Repository with.sun.faces.context.Ajaxexceptionhandlerimpl handlePartialResponseError

Question

Guys, I’m going through a problem here, and I can’t solve it. I’ve looked in the forums, but I haven’t seen any solutions either. Anyone gives this help?

The error happens when I try to save the folder with the user data. I thought I might be sending the null user object, but I’ve verified that’s not it.

I have checked many times to see if I forgot to initialize some instance or object variable, but also found nothing wrong.

stracktrace indicates that the error is on line 27, in the call serviceUser.adduser(user);

Caused by: java.lang.NullPointerException
    at br.com.jamming.controller.RegisterUserMB.save(RegisterUserMB.java:27)

Does anyone know what may be going on? I appreciate the availability.

Magagedbean:

@ManagedBean
@RequestScope
public class RegisterUserMB {

    @Autowired
    private UserService userService;

    private User user = new User();

    private String confirmPw;

    public String save() {
        userService.addUser(user);
        return "";          
    }

Service:

@Service
public class UserService {

    @Autowired
    UserRepository<User> userRepository;

    @Transactional
    public boolean addUser(User user) {
        return userRepository.save(user) != null;
    }

Repository:

public interface UserRepository<U> extends CrudRepository<User, Long> {


}

xhtml:

                        <p:inputText id="cellphone" value="#{registerUserMB.user.cellphone}" placeholder="Cellphone"/>

Thank you!!
