Is there anyway I can see some code for this, when I create an
arraycollection I keep getting errors:
public var myList:ArrayCollection = new ArrayCollection();
public function personJSON(event:ResultEvent):void
{
var rawData:String = String(event.result);
var person:Object = JSON.decode(rawData);
trace(person[0].item1);
trace(person.length);
var x:Number;
for(x=0;x<person.length;x++){
trace(person[x].item1);
// myList.push(person[x].item1);
myList.getItemAt(person[x].item1);
