File Progress event
Hi
i have copied this code off the flex site https://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/FileReference.html#event:progress <https://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/FileReference.html#event:progress>
but the progress does not seem to fire,
private function saveReport():void {
cursorManager.removeBusyCursor();
var buffer:ByteArray = myPDF.save(Method.LOCAL);
var file:FileReference = new FileReference();
configureListeners(file);
file.save(buffer, "Overview Report.pdf");
}
private function configureListeners(dispatcher:IEventDispatcher):void {
dispatcher.addEventListener(ProgressEvent.PROGRESS, progressHandler);
}
protected function progressHandler(event:ProgressEvent):void
{
var file:FileReference = FileReference(event.target);
trace("progressHandler name=" + file.name + " bytesLoaded=" + event.bytesLoaded + " bytesTotal=" + event.bytesTotal);
}

I suppose AV software could result in a similar problem on Mac. If you
are running AV, try disabling it.
Another thing to do is get the current time at the save() call and then
when the "complete" event comes in to see if it matches the observed time
to save.
I noticed you said "download" but aren't you using the "save" method?

Hi Scott,
Are you running on Windows with anti-virus software? See this post [1].
I've had similar experiences with Flash/AIR and File I/O. To the runtime,
the write happens quickly, into a memory buffer, then the AV software
takes 1-2 mins to scan it before writing it.

Re: File Progress event
Posted by Alex Harui <ah...@adobe.com.INVALID>.
How big is the buffer ByteArray and where are you writing the file? If
the write can happen fast enough, no Progress events are fired. From the
link you posted:
"In some cases, progress events are not received. For example, when the
file being transmitted is very small or the upload or download happens
very quickly a progress event might not be dispatched."
