I've created a Spring Boot web application that takes in a filepath into the search bar and outputs the files at that filepath. The output is rendered on the same page, just below the search bar. I would like the input to the search bar (the filepath) to be kept as is on the output page, but instead it is replaced with a string of the files contained at that filepath. How can I fix this?

{
@GetMapping("/")
public String showForm(Model model) {
Filename filename = new Filename();
model.addAttribute("filename", filename);
return "register_form";
}
@PostMapping("/register")
public ModelAndView submitForm(@ModelAttribute("filename") Filename filename, @ModelAttribute("original") Filename original) {
ModelAndView view = new ModelAndView("register_form");
view.addObject("filename", filename);
view.addObject("original", original); // here
return view;
}
}
