About PictureFillSymbol

I using ArcGIS API for flex 3.2+flash builder 4.6
I want to draw a Bitmap on a map. I used the PictureFillSymbol, but the polygon didn't been filled by the Bitmap, the polygon is empty. Can you help me?
My codes :

Use the agslib-3.0-2012-06-06.swc won't have the problem .
The agslib-3.2-2013-03-19.swc will have the problem .

Hi,

There is actually a bug, thanks for reporting.
I have a workaround in the meantime.
Encode the BitmapData into a ByteArray, like this:

var pngEncoder:PNGEncoder = new PNGEncoder();
var bmd:BitmapData = new BitmapData(30, 30, true,0x10ff0011);
var bytes:ByteArray = pngEncoder.encode(bmd);
var fill:PictureFillSymbol = new PictureFillSymbol();
fill.source = bytes;
fill.outline=sls;
fill.width = 30;
fill.height = 30;
