패널 내의 Flex 렌더러 데이터

Question

XML 파일 (아래)에서 반환 된 "항목"을 나열하는 데이터 격자가있는 페이지 (아래)가 있습니다.로드 할 때 각 항목의 뷰 스택에 페이지가 생성되었습니다 발견 (작동) 그것은 또한 각 패널 안에 페이지 (아래) 렌더링하지만 데이터를 전달하는 데 문제가 있습니다. 각 페이지는 렌더링되고로드되지만 XML 데이터의 첫 번째 결과는 각 페이지가 자체 데이터를 가지지 않고 모두 첫 페이지와 동일합니다.

Answer 1

이 문제를 일으키는 지 잘 모릅니다하지만 다음과 같습니다

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); 
     } 
    } 
} 

개

요구 사항이있을 수 있습니다 :

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); 
    } 
    } 
} 

을 정말 당신은보기가 전체 항목을 스택에 합격하고 그것을 개별 속성을 보내는 대신 필요한 것을 보자한다.
