현재 TableTree를 구현하려고합니다. 하지만 어쨌든 노드를 확장하지는 않습니다. 나는 이것이 어떻게 일어날 수 있는지에 관해 아무것도 발견하지 못했습니다. 내 데모 - 설정에는 내 루트 노드의 하위 노드로 렌더링되어야하는 데이터가 포함되어 있습니다. 개찰구 코드를 통해 스테핑개찰구 6.5.0 : DefaultTableTree가 확장되지 않습니다
노드가 결코 EXPANDED
요소 OrderItem의 설정이 OrderWrapper -Entities을 표시하는 루트로의 상태를 변경하지 밝혔다.
다음은 관련 코드입니다. 더 많은 정보가 필요하다면 최선을 다해 제공 할 것입니다.
