HTTPService/ResultEvent with Flex 3.2 versus Flex >= 3.5
- by Julian
Hey everybody,
through a design decission or what-so-ever Adobe changed the content of the ResultEvent fired by a HTTPService Object.
Take a look at 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 with Flex 3.5 or Flex 4.0 event.target as HTTPService is null.
I figured out that event.target is now an instance of HTTPOperation. That is interesting because I can't find HTTPOperation in the langref. However, I think what Flash Builder's debugger means is mx.rpc.http.Operation.
The debugger also shows that event.target has a private attribute httpService which is the instance I expected to get with event.target. But it's private, so event.target.httpService doesn't work.
If I only want to remove the EventListener I can cast event.target as EventDispatcher. But I need to use methods from HTTPService.
So: How can I get the HTTPService instance from the ResultEvent?
Any help would be appreciated. Thanks!
J.
