ActionScript 3.0 :: GetBmpData Returns Null When The SWF Is Accessed On The Remote Server?

The Document class loads a list of external bitmap images. As the images are loaded, the following takes place for each:

Code:
var obj:Object = new Object();
obj.bmpData = bmp.bitmapData;
obj.bmpFilename = bmpFilename;
bmpDataList.push(obj);

As you can see, an object is created and the bitmapData is stored inside of it. This object is added to an array.Later, when a key is pressed, a new instance of a class is created. A function is called that retrieves the appropriate bitmapData and this is passed to the constructor of the new instance. Example:

Code:
//Instance is created:
var newChar:BaseChar = new LowA(getBmpData("a"));[code]....

The problem is that getBmpData returns null when the SWF is accessed on the remote server. Result = no images seen. It works just fine locally.
