HTTPService / ResultEvent with Flex 3.2 and Flex> = 3.5

Question

Adobe has changed the contents of the ResultEvent launched by the HTTPService object through design dividing or something-ever.

Take a look at the following example:

var httpService:HTTPService = myHTTPServices.getResults();
httpService.addEventListener(ResultEvent.RESULT,resultHandler);
httpService.send();

/**
 * Handels the login process
 */
function resultHandler(event:ResultEvent):void
{
    // get http service
    var httpService = (event.target as HTTPService);

    // do something
}

It works like a charm with Flex 3.2. But when I try to compile it using Flex 3.5 or Flex 4.0 event.target, since the HTTPService is null.

I realized that event.target is now an instance of HTTPOperation. This is interesting because I cannot find HTTPOperation in langref. However, I think the Flash Builder debugger means mx.rpc.http.Operation.

The debugger also shows that event.target has a private attribute httpService, which is an instance that I expected to receive from event.target. But it is private, therefore event.target.httpService does not work.

EventListener, event.target EventDispatcher. HTTPService.

: HTTPService ResultEvent?

. HTTPService , AbstractOperation. , request, Object:

myService.request["service"] = myService;

, HTTPOperation event.currentTarget, HTTPService :

 var eventService : HTTPService = HTTPService( AbstractOperation( event.currentTarget ).request["service"] );
