Trouble with DataEvent.UPLOAD_COMPLETE_DATA not firing

I am having some trouble with an AS3 script to upload data to the server via PHP and then return some values from the PHP upload script. I am using the FileReference.uplo开发者_JAVA百科ad() function, and the files are being successfully uploaded, but the eventListener I attached to the DataEvent.UPLOAD_COMPLETE_DATA event is not triggering. Is there something I can do on the PHP end of things to manually trigger this event when the file is done uploading?

as3:

private function onFileLoaded(event:Event):void {
            //var _fileReference:FileReference = event.target as FileReference;
            //var data:ByteArray = fileReference["data"];
            //var filename:String = fileReference.name;
            var urlRequest:URLRequest = new URLRequest("http://www.arttoframes.com/canvasSystems/uploadImage.php");
                urlRequest.method = URLRequestMethod.POST;                  
            fileReference.addEventListener(DataEvent.UPLOAD_COMPLETE_DATA, onUploadComplete);
            fileReference.upload(urlRequest);
        }
        private function onFileLoadError(event:Event):void  {
            fileReference.removeEventListener(Event.COMPLETE, onFileLoaded);
            fileReference.removeEventListener(IOErrorEvent.IO_ERROR, onFileLoadError); 
        } 
  private function onUploadComplete(event:Event):void {
            trace("ok");
            fileReference.removeEventListener(DataEvent.UPLOAD_COMPLETE_DATA,onUploadComplete);
            var thumbReferenceName = fileReference.name.substr(0,fileReference.name.indexOf("."))+"_thumb"+fileReference.name.substr(fileReference.name.indexOf("."),4)+"?nocache=" + new Date().getTime()
            var urlRequest:URLRequest = new URLRequest("http://www.arttoframes.com/canvasSystems/uploads/Thumbnails/"+thumbReferenceName);
            var urlLoader:Loader = new Loader ();
                urlLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onDownloadComplete);
                //urlLoader.load(urlRequest);
        }

So this is a long standing bug that Adobe claims they've fixed, but at least in Flex 3 lots of people claim they can reproduce it even after Adobe says they've fixed it. And that's including yours truly.

I'd employ a work around monitoring the progress directly and when all of it has uploaded manually dispatch the event or just do your work there. There are several work arounds you can try reading the comments in Jira.
