I’ve had several problems with this that only affect the Mac version of the Flash Player – so frustrating – the joy of the Flash Platform is supposed to be that you don’t have disparate platforms to test! Anyhow if you’re struggling with this…

Add an extra output from the server to trigger onComplete on a Mac as outlined in Abdul Qabiz’s lovely post here:

Our ASP.NET backend had no trouble with this and even though the onComplete function was not the one throwing the error in my AS – fixing this seemed to have a domino effect of pleasurable error freeness. One point of note; contrary to many posts I have read; this deos not appear to be fixed in Flash Player 9 for Mac so do it anyway (can’t hurt)

Also maybe try:

- Making sure the FileReference Object never drops out of scope/gets removed too early

- Making sure you have a handler for onCancel (good for debugging)

- Using Delegate.create to specify the instance to handle:

this.referenceListener.onSelect = Delegate.create(this, refOnSelect);

Also be aware that you basically can’t send data back with the onComplete event:

We created a getUploadStatus Web Service that we called aftewards with the same UID we’d posted alomg with the upload to get around this.

P.S There is a FileReference.onUploadCompleteData event but it only works in Flash 9.0.28 and up…
