httpservice를 ActionScript 클래스에서 쿼리

Question

내 httpservice (AS 클래스에서 정의 됨)에서 my mxml 응용 프로그램으로 결과를 얻으려고합니다. 모든 코드를 주 mxml에 넣었을 때 코드 자체가 잘 작동하지만 AS 클래스에서 작동하지 않는 것처럼 보입니다.

httpresult (myWatchedList = new XMLListCollection (myData.movie);)를 가져 오는 줄에 중단 점을 넣으면 myWatchedList에 원하는 값이 있음을 확인할 수 있습니다. 그러나 getWatchedList() 메소드를 호출하면 myWatchedList는 항상 null입니다.

내가 여기에 매우 뭔가를 분명 누락 확신 ... 클래스 AS

내 :

package components 
{ 

import mx.collections.XMLListCollection; 
import mx.rpc.events.ResultEvent; 
import mx.rpc.http.HTTPService; 

public class WatchList 
{ 
    [Bindable] 
    public var myToWatchList:XMLListCollection; 
    public var myWatchedList:XMLListCollection; 

    public function WatchList() 
    { 
     //httpservice for watched movies 
     var watchedList_service:HTTPService = new HTTPService(); 
     watchedList_service.url= "http://*****/phpscripts/selectWatchedlist.php"; 
     watchedList_service.showBusyCursor=true; 
     watchedList_service.resultFormat="e4x"; 
     watchedList_service.method="POST"; 

     //httpservice for not yet watched movies 
     var toWatchList_service:HTTPService = new HTTPService(); 
     toWatchList_service.url= "http://*****/phpscripts/selectToWatchlist.php"; 
     toWatchList_service.showBusyCursor=true; 
     toWatchList_service.resultFormat="e4x"; 
     toWatchList_service.method="POST"; 

     //listen for result 
     watchedList_service.addEventListener(ResultEvent.RESULT, watchedList_result); 
     toWatchList_service.addEventListener(ResultEvent.RESULT, toWatchList_result); 

     //send request to httpservice 
     toWatchList_service.send(); 
     watchedList_service.send();  

    } 

    public function toWatchList_result(event:ResultEvent):void 
    { 
     //result is xml 
     var myData:XML = XML(event.result); 
     myWatchedList = new XMLListCollection(myData.movie); 
    } 

    public function watchedList_result(event:ResultEvent):void 
    { 
     var myData:XML = XML(event.result); 
     myToWatchList = new XMLListCollection(myData.movie); 
    } 

    public function getWatchedList():XMLListCollection { 
     return this.myWatchedList; 
    } 

    public function getToWatchList():XMLListCollection { 
     return this.myToWatchList; 
    } 
} 
}

Answer 1

먼저 요청을 한 생성자를 호출하십시오.

결과를 가져올 수 있습니다 이벤트를 던져 대기 핸들러합니다

myToWatchList = watchList.getToWatchList(); 

이 ... 당신이 요청이 완료 될 때까지 예를 들어, 기다려야한다 :

watchList= new components.WatchList(); 

은 즉시 그 후 당신은 결과를 전화 이벤트의 경우
