Arrays in Eventhandling function

Question

Hi
I just created one flex application using <mx:http>  tag with resultHandler event  function
<mx:HTTPService id="employees" url =" c:/sai/one.xml" result="resultHandler(event)"  fault="httpFaultHandler(event)"
resultFormat="e4x"
/>
private function resultHandler(event:ResultEvent):void
   var  custresultdata:XMLList=new XMLList();
   var labelsArray:Array /* of String */ = new Array(custresultdata.length);
          var index : int = 0;
          var i:int=0;
          custresultdata=event.result.customer; 
   for each (var labelText:String in custresultdata)
                         labelsArray[index++] = labelText;
                    aa=labelsArray;
i=aa.length;
Alert.show(p.toString());/       *here it  showing the length is 5 */
my problem is the function returning data to array named as aa,but  when i try to assigning the same array aa to another array hh out side of this function,the array hh is not contaning data
public function init():void
   employees.send();
   hh=aa;
   p=hh.length;
   Alert.show(p.toString());  /*here it  showing the length is 0 */
here i am posting the entire code of my application,
how can i slove this problem
thanks in advance

Try this, way of intializing hh value. Because Flex follow asynchronous process of execution.
public function init():void
   employees.send(); 
private function resultHandler(event:ResultEvent):void
   var  custresultdata:XMLList=new XMLList();
   var labelsArray:Array /* of String */ = new Array(custresultdata.length);
          var index : int = 0;
          var i:int=0;
          custresultdata=event.result.customer; 
   for each (var labelText:String in custresultdata)
                         labelsArray[index++] = labelText;
                    aa=labelsArray;
hh=aa;
p=hh.length;
Alert.show(p.toString());
