My problem wasn't receiving null...
I send an HTTPService. The ResultEvent creates an ArrayCollection. I wanted my
class to return that ArrayCollection but what is happening is right after my
HTTPService is sent, my class returns my ArrayCollection before the ResultEvent
has time to fill it... therefore it is null....
I'm now trying to implement an EventDispatcher but am getting a little
confused...
Does this look right??? :
[
{
{
service.url =
service.useProxy =
service.method =
service.resultFormat =
service.showBusyCursor =
service.addEventListener(ResultEvent.RESULT, Bindable]
publicclassClientServices
extendsEventDispatcherprivatevarserviceArray:ArrayCollection;privatevarserviceXML:XML;
publicfunctionClientServices
(target:IEventDispatcher=null)super(target);varservice:HTTPService =
newHTTPService();'test.php';false;'POST';'e4x';true;function(event:ResultEvent):void{
serviceArray =
serviceXML = event.result
dispatchEvent(event)
}
);
service.send();
}
}
Thanks.newArrayCollection();asXML;varourxml:XML;foreach(ourxml
inserviceXML.elements()) serviceArray.addItem(ourxml);

If you are having problems with it giving you a null object before the
ResultEvent function is called then make a function that returns an empty
ArrayCollection if it is currently null.
Perhaps
function getServiceArray( ):ArrayCollection
{
if( this.serviceArray == null )
{
this.serviceArray = new ArrayCollection( );
}
return this.serviceArray( );
}
If that isn't what you are having problems with, perhaps more specificity could
help us help you.
