Using Async to wait for a specific event

Question

I've simplified the creation and deletion calls and used a generic item.  In my before method, I call Async.handleEvent to wait for PropertyChangeEvents, but this only waits for the first one.  My problem lies in the fact that ItemManager is an IEventDispatcher that sends multiple property change events, but I need to wait for the specific event with the property "item".  However, when I call Async inside the handler, it does not keep the Test method from running, Before assumes that it's Async responsibilities have been fulfilled and launches the next stage of tests.  How can I keep Before from moving on until an event with a specific property has been received?
public class Test
        private static const TIME_OUT:int = 3000;
        [Before(async)]
        public function runBeforeEveryTest() : void
            // Create a new item
            item.create();  // This is an asynchronous creation that sends many Property Change events
            //Wait for the item to be created before continuing tests.
            Async.handleEvent( this, ItemManager.instance, PropertyChangeEvent.PROPERTY_CHANGE, handlePropertyChangeForItem, TIME_OUT);
        [After]
        public function runAfterEveryTest() : void
            // Delete the Item
            item.delete();
        [Test(async)]
        public function itemExists() : void
                  Assert.assertTrue( item.exists() );
       private function handlePropertyChangeForItem(evt:PropertyChangeEvent, eventObject:Object) : void
             if (evt.property == "item")
                 // Now that the item has been created, we can start the tests.
                 return;
             else
                 // Keep waiting.
                 Async.handleEvent( this, ItemManager.instance, PropertyChangeEvent.PROPERTY_CHANGE, handlePropertyChangeForItem, TIME_OUT);
Thanks in advance, it's greatly appreciated!

I can't reproduce this issue. All seems to be working fine with multiple deferred Async calls. I am pasting my code in. Since I did not have your manager, I tried to repiicate this with a timer. If you could look at my code and see if it differs from yours in a significant way, I can take another shot, but it seems to be working as expected.
package  
import flash.events.TimerEvent; 
import flash.utils.Timer; 
import mx.events.PropertyChangeEvent; 
import org.flexunit.Assert; 
import org.flexunit.async.Async; 
public class NestedAsync { 
private static const TIME_OUT:int = 3000; 
private var timer:Timer; 
Before(async)]
public function runBeforeEveryTest() : void {   timer =
new Timer( 1000, 5 ); 
  Async.handleEvent(this, timer, TimerEvent.TIMER, handleTimerTick, TIME_OUT);timer.start();}
[After]
public function runAfterEveryTest() : void {  timer.stop();
  timer =
null;}
Test(async)] 
public function itemExists() : void {Assert.assertTrue(
true );}
private function handleTimerTick(evt:TimerEvent, eventObject:Object) : void {  
  if ( timer.currentCount == 5 ) { 
    // Now that the item has been created, we can start the tests. 
    return;  }
  else  { 
    // Keep waiting.    Async.handleEvent(
this, timer, TimerEvent.TIMER, handlePropertyChangeForItem, TIME_OUT);
