Using FileReference.browse or FileReference.download ?
In the work flow, if you were using FileReference.browse or FileReference.download, the script replay can fail if you are using the Flash player 10.
Flash player 10 security features does not allow action script level programatic reply of events which triggers the above operations. i.e These operations work only if it was triggered by the user interaction such as actual mouse click or keyboard click.
Since the automation framework replay happens at the action script level (using the low level events being dispatched on the targets), this will be blocked by the security restriction.
The flash player 10 security enhancement documentation states “In Flash Player 9, ActionScript could perform uploads and downloads at any time. With Flash Player 10, the FileReference.browse and FileReference.download operations may be initiated only through ActionScript that originates from user interaction. This includes actions such as clicking the mouse or pressing the keyboard. “
