스프링의 소스인 BindTag.java안에 있는 해당 메소드를 검색해보니 익셉션이 아래와 같은 경우에 생성이 되었다.

protected final int doStartTagInternal() throws Exception {

....

        try {
            this.status = new BindStatus(getRequestContext(), resolvedPath, isHtmlEscape());
        }
        catch (IllegalStateException ex) {
            throw new JspTagException(ex.getMessage());
        }

.....

    }

그 전까지는 저런 익셉션 없었는데,
업데이트문을 하나 추가하고 난 뒤에 벌어진 일이라, 업데이트 문의 문제라고 생각했었다.
그래서 쿼리에 문제가 있었다고 생각했는데 디버깅한다고 다 찍어보니 그건 아니었다.

문제는 해쉬맵에 있었다.
나름 별도로 띄워두겠다고 컨트롤러내에서 내가 따로 정의한 Map을 리턴하게 해둔 메소드에서
null을 리턴하고(당당히 return null;이라 적었음),
view에선 해당 맵을 찾고 있으니 생각해보면 당연한 오류였다.

이런 멍청한 행동은 하지 말아야지;;;
