Description

Steps to reproduce:
1. Extract the attachment I attached.
2. Run the bin-debug/Test.html (Do not import to flash builder as it may re-compile and overwrite the one compiled from my side)
3. You should see the preloader does not show up.

Actual Results:
The preloader does not show up. I tested on firefox and IE, both have this problem.

Expected Results:
The preloader suppose to show up by default

Workaround (if any):
I tried to explicitly set it like this: preloader="mx.preloaders.SparkDownloadProgressBar". This still doesn't work.
I tried to set it like this: preloader="mx.preloaders.DownloadProgressBar", using the older preloader. This showed up correctly.
