Neither BindingResult nor plain target object for bean name 'id' available as request attribute

I keep getting the "Neither BindingResult nor plain target object for bean name 'id' available as request attribute" error when try to add the related user iterating through the loop. 

 @RequestMapping(value = "/user", method = RequestMethod.GET)
public String getUser(HttpServletRequest request, HttpServletResponse response, Model model,  @RequestParam("id") String id, @ModelAttribute("userForm") UserForm userForm)
{
    User user = userService.getUser(id);
    List<User> relateUsers = userService.getRelatedUsers(id);
    userForm.setUser(user);
    userForm.setRelateUsers(relateUsers);
    return userDetailForm;

}



<div class="trackList" th:if="${userForm.relatedUsers.size() > 0}" th:each="relatedUser : ${userForm.relatedUsers}"  >

<th:form method="POST" th:action="@{/user}">                              
              <input type="hidden" id="id" th:field="*{id}"/>
                <div>
              <a class="add"  role="button">Add</a>
                        </div>
</th:form>


</div>

It helped me to bind value to model attribute, using this code :

<input type="hidden" th:id="id" th:name="id" th:value="*{id}"/>

Your example is weird because your handler just maps to a GET request. Anyway, your method signature of your POST handler is invalid in respect to BindingResult.

Spring Framework documentation says:

org.springframework.validation.Errors / org.springframework.validation.BindingResult validation results for a preceding command or form object (the immediately preceding method argument).

You have to change method signature of your POST handler from something like that

@Valid @ModelAttribute("userForm") UserForm userForm, @RequestParam("id") String id

to

@Valid @ModelAttribute("userForm") UserForm userForm, BindingResult result, @RequestParam("id") String id
