Flex renderer data inside a panel...

Question

I have a page (below) that has a datagrid that lists "item"'s returned from an XML file (below) and when it loads it created a page in the viewstack for each item it finds (working) it also renders a page (below) inside each panel but i am having issues passing the data. Each page renders and loads but with the FIRST result of the XML data instead of each page having its own data they all have the same as the first page.

Answer 1

dont know if this is causing the problem but it looks like this :

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);
       }
    }
 }

needs to be this:

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);
    }
  }
}

and really you should pass the view stack the whole item and let it take what it needs instead of sending it individual properties.
