    Unhappy Please help me with XMLList upgrade...

    Hi all, I need Your help with something in my code....

    Here is my code:
    ******************************************
    Code:
    import mx.controls.Alert;
    import mx.rpc.events.ResultEvent;
    import mx.rpc.http.HTTPService;
    
    public class Controler{
    
    [Bindable]
    public var lista:XMLList;
    
    public function consult():XMLList{
         var service:HTTPService = new HTTPService();
         service.url="http://localhost/Something.php";
         service.useProxy=false;
         service.resultFormat="e4x";
         service.addEventListener(ResultEvent.RESULT, met);
         service.send();	
         Alert.show(lista.length()); 	//prints 0 =S
         return this.lista;
    }
    
         private function met(event:ResultEvent):void{
         lista = event.result.option as XMLList;
         Alert.show(this.lista.length()); //prints the real value, actually: 6	
         }
    }
    **********************************************

    The thing is: I got data from a database, working fine, in the function met I got the data and the alert.show shows the length of the var lista:XMLList wich is [Bindable] but when i used again in the consult function I got a big 0 (zero) and I dont know what the problem is, some help please...

    well I know the problem is that the var lista:XMLList dont make the upgrade but I dont know why...

    It seems like you're running into a race condition. Flex is asynchronous -- it will continue to execute your function while the event fires. So, don't handle the list in your consult() function. Have ] your met() function trigger the next step for your logic.
