querydsl where 절 조건 관련 오류 문의드립니다.

안녕하세요..

강의 잘 듣고 여러모로 아주 도움이 많이 되고 있습니다. 

페이징 처리하는데 있어서 조건검색을 2개는 or 로. 1개는 and 조건으로 처리하고 싶은데 

companyName, companyArea, Status 

이렇게 3개의 조건을 받아서 처리하는데 

null point exception 오류가 납니다. 

where 절 이부분에서  

            .where(
                    ( companyNameEq(keyword)
                     .or(companyAreaEq(keyword))
                    ),
                    statusEq(status)
            )

.or(companyAreaEq(keyworkd) 을 빼면 오류가 안납니다. 

물론 그위에 companyNameEq를 빼도 안나고요.. 

먼가 조건 조합 할 때의 오류인듯한데 이리저리 해봐도 계속 오류가 나서 

바쁘시지만 조언을 좀 구했으면 합니다 ^^
