dati renderer Flex all'interno di un pannello

Question

Ho una pagina (in basso) che ha un datagrid che elenca "voce" s 'tornato da un file XML (in basso) e quando lo carica ha creato una pagina nel ViewStack per ogni elemento che trova (di lavoro) ma anche rende una pagina (in basso) all'interno di ciascun pannello, ma io sto avendo problemi di passaggio dei dati. Ogni pagina rende e carica, ma con il primo risultato dei dati XML, invece di ogni pagina con il proprio i dati hanno tutti la stessa della prima pagina.

Non so se questa è la causa del problema, ma sembra che questo:

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);
       }
    }
 }

deve essere questo:

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);
    }
  }
}

e davvero si dovrebbe passare la vista pila tutta la voce e lasciarlo prendere ciò di cui ha bisogno invece di inviarlo proprietà individuali.
