[ValidationException: HV000041: Call to TraversableResolver.isReachable() threw an exception.]

Play Framework todolist 예제를 따라하다가 발생한 에러

검색해보면 setter/getter를 추가해라는 답변도 있는데, 콘솔 에러를 보면

> cd todolist
> play
[todolist] $ run

There is no need to compile the code yourself or restart the server to see the modification. It is automatically reloaded when a change is detected.
