안녕하세요, 정중한 개구리 님. 공식 서포터즈 y2gcoder 입니다.

말씀해주신 예외만 봤을 때는 해당 자바스크립트 인라인 강의에서 생성한 부분이 아니라 이전 강의 중 하나인 조건부 평가 챕터에서 생성하신 BasicController와 basic/condition.html 부분을 확인해봐야 할 것 같습니다.

두 코드 전문을 보여주시면 감사하겠습니다 :)

특히 BasicController에서

@GetMapping("/condition")
  public String condition(Model model) {
      addUsers(model);
      return "basic/condition";
  }

해당 코드와, addUser() 메서드, 내부 클래스인 User 클래스의 코드와 basic/condition.html 를 중점적으로 봐야 할 것 같습니다!

감사합니다.
