저는 jsf에서 웹 응용 프로그램을 개발했습니다. 세션을 사용하여 다른 페이지의 개체에 액세스했습니다. 무엇보다도 먼저 다른 사용자 객체를 원한다. 세션에서 다른 키 이름으로 객체를 저장했지만 두 번째 객체를 저장하는 동안 첫 번째 객체를 대체하고있다. 다른 키 이름. 어떻게하면이 문제를 해결할 수 있을까요?JSF 세션은 동일한 객체를 다른 키에 저장하면서 기존 객체를 대체합니까?

이 내가 두 번째 사용자 개체를 가져 오지하기 위해 pickedUser를 사용하고 여기 내 관리 빈이지만이 사용자 객체를 대체합니다.
피커 콩 내가 키 pickedUser 와 세션에서 두 번째 사용자를 stroing있어 여기 여기

이지만 기존 하나를 교체합니다.
감사합니다.
