Richfaces 4 - extendedDataTable 내장 된 필터링 - 필터링 적용 후 selectionListner가 업데이트 된 인덱스를 가져올 수 없습니다.

Question

Richfaces 4 - extendedDataTable inbuilt 필터링 - selectionListner()는 필터링이 적용된 후 업데이트 된 인덱스를 가져올 수 없습니다. Richfaces 3에는 richfaces 4에없는 DataModel 클래스가 있습니다. RichList 4에서 테이블 필터링을 구현하는 가장 좋은 방법은 selectionListner()도 올바르게 작동하도록하는 것입니다.

Answer 1

나는이 문제 때문에 @ViewScoped입니다 생각합니다.

@SessionScoped을 사용해보세요. 문제를 해결해야합니다.
