Springs form null values - spring

Question

I have a small problem with my form in spring, it is a simple form with title, username and password, validation works as if I try to submit an empty form I get an error however if I input values in and submit the form, it is submitted but it displays that values inserted are "null".
Domain:
#Entity
public class User {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String title;
#NotNull
#Size(min=2, max=30)
private String username;
#NotNull
#Size(min=6)
private String password;
public String getTitle() { return title; }
public String getUsername() { return username; }
public String getPassword() { return password; }
public Long getId() { return id; }
public void setId(Long id) {
this.id = id;
}
public void setUsername(String username) { this.username = username; }
public void setPassword(String password) { this.password = password; }
public void setTitle(String title) { this.title = title; }
public List<Note> getNotes() {
return notes;
}
#OneToMany
private List<Note> notes = new ArrayList<Note>();
}
Form:
<form action="#" th:action="#{/create/user}" th:object="${user}" method="post">
<input type="hidden" th:field="*{id}" />
<p>Title: <input type="text" th:field="*{title}" /></p>
<p>Username: <input type="text" th:field="*{username}" /></p>
<p>Password: <input type="password" th:field="*{password}" /></p>
<p><input type="submit" value="Submit" /></p>
</form>
<div class="form-group">
<ol class="list-group">
<li class="list-group-item list-group-item-info" th:each="user : ${user}">
<span th:text=" ${user.title} + ${user.username} + ${user.password} "></span>
delete
</li>
</ol>
</div>
Controller:
#Controller
public class UserController {
#Autowired
protected UserService userService;
#RequestMapping(value = "/create/user", method = RequestMethod.POST)
public String createUser(Model model, #Valid #ModelAttribute("user") User user, BindingResult bindingResult){
if(bindingResult.hasErrors()){
model.addAttribute("user", user);
model.addAttribute("users", userService.findAll());
model.addAttribute("type", "danger");
model.addAttribute("message", "Please fill in all the fields" +
"Username needs to be at least 2 characters" +
"Passwords needs to contain at least 6 characters");
return "user";
}
userService.save(user);
model.addAttribute("user", new User());
model.addAttribute("cards", userService.findAll());
model.addAttribute("type", "success");
model.addAttribute("message", "A new user has been added");
return "user";
}
If any additional code in needed please let me know, I am still newbie in Spring

Found an error by reviewing the code:
In the form when outputting registered users it was:
<li class="list-group-item list-group-item-info" th:each="user : ${user}">
While it should be:
<li class="list-group-item list-group-item-info" th:each="user : ${users}">
