패널 내부의 렌더러 데이터

Question

XML 파일 (아래)에서 반환 된 "항목"이 나열된 DataGrid가있는 페이지 (아래)가 있는데,로드하면 각 항목에 대한 viewStack에서 페이지를 만들었습니다. (아래) 각 패널 내부에 있지만 데이터를 전달하는 데 문제가 있습니다. 각 페이지는 렌더링 및로드이지만 각 페이지 대신 자체 데이터를 갖는 대신 XML 데이터의 첫 번째 결과를 사용하면 모두 첫 페이지와 동일합니다.

Answer 1

이것이 문제를 일으키는 지 모르지만 다음과 같이 보입니다.

private function httpResult_handler(evt:ResultEvent):void {
     if (evt.result.software.item) {

       httpData = XML(evt.result).descendants("item");
       var item:Object = httpData;
       for each(item in httpData) {
          viewstack_addChild(item.name);
       }
    }
 }

이것이어야합니다 :

private function httpResult_handler(evt:ResultEvent) :void {
  if(evt.result.software.item){
    var httpData:XMLList = XML(evt.result).descendants("item");
    for each(var item:Object in httpData){
      viewstack_addChild(item.name);
    }
  }
}

그리고 실제로 뷰를 전체 항목을 쌓아서 개별 속성을 보내는 대신 필요한 것을 가져 가야합니다.
