Well, thank God I have the source code for ProgressBar.as
I tracked it down to this:
if (_indeterminate && _source == null && _mode ==
ProgressBarMode.EVENT && visible)
startPlayingIndeterminate();
else
stopPlayingIndeterminate();
So, if you set ProgressBar.source then animation will never work. The
only way you can get this to work is to set ProgressBar.mode =
"event", but don't attach a source. Attach your own ProgressEvent
listener to your source. When you first hit that event do something
like this:
private function onProgress(e:ProgressEvent):void {
if(progressBar.indeterminate) {
trace("setting indeterminate to false");
progressBar.indeterminate = false;
progressBar.mode = "manual";
}
progressBar.setProgress(e.bytesLoaded, e.bytesTotal);
}
Now, you have to set it back to "manual" mode so you can update the
progress -- pretty screwy...but it works.
