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

Question

From what I can tell this is set up correctly but I am getting the following error:

java.lang.IllegalStateException: Neither BindingResult nor plain target 
         


        

Answer 1

First I had the form in index.html

 @RequestMapping(value = "/", method = RequestMethod.GET)
    public String indexPage(){
        return "index";
    }

So when my form:

Was looking for / it was hitting the above method, NOT:

@RequestMapping(value="/", method=RequestMethod.GET)
    public String contactForm(@Valid @ModelAttribute("person") Person person, BindingResult bindingResult,
                              HttpServletRequest request, Model model) throws IOException {

        if(bindingResult.hasErrors()){
            System.out.println("There was a error "+bindingResult);

            return "index";
        }

        model.addAttribute("person", new Person());
        return "index";
    }

Which was correct!

I had to remove the first method and it worked.
