Error Rendering View[페이지경로/페이지명(확장자포함)] 에러시 해결방안에 대해 알아본다.
PrimeFaces의 menubar를 이용하여 아래와 같이 MenuModel을 사용해 메뉴를 생성했고,
화면에서 생성된 메뉴를 클릭했는데 위와 같은 렌더링 에러 발생.
MenuModel menu = new DefaultMenuModel();
DefaultSubMenu commonSubMenu = new DefaultSubMenu();
DefaultMenuItem menuItem = new DefaultMenuItem();
menuItem.setValue(aiomenum.getMenuNm()); //메뉴명
menuItem.setParam(PAGE_URL, aiomenum.getAccessUrl()); //접속URL
menuItem.setCommand(DISPLAY_MOVE); //커멘드입력
commonSubMenu.addElement(menuItem);
menu.addElement(adminSubMenu);
◆ 원인
메뉴에 ID값을 할당하지 않아서 렌더링이 에러가 발생.
◆ 해결방안
메뉴객체에 고유한 ID를 할당한다.
generateUniqueIds();
MenuModel menu = new DefaultMenuModel();
DefaultSubMenu commonSubMenu = new DefaultSubMenu();
DefaultMenuItem menuItem = new DefaultMenuItem();
menuItem.setValue(aiomenum.getMenuNm()); //메뉴명
menuItem.setParam(PAGE_URL, aiomenum.getAccessUrl()); //접속URL
menuItem.setCommand(DISPLAY_MOVE); //커멘드입력
commonSubMenu.addElement(menuItem);
menu.addElement(adminSubMenu);
menu.generateUniqueIds(); //고유ID 할당
◆ 전체에러 메세지
