flex4

I have a flex4 applciation (mx+spark). When I use:

FlexGlobals.topLevelApplication.styleManager.loadStyleDeclarations(skinName, true);

This works fine: new style is applied.

The trouble is when I apply a new style, it mixes both: this happens because I need to Unload style first.

I try to unload it with:

FlexGlobals.topLevelApplication.styleManager.unloadStyleDeclarations("style/normal.swf",false);

And I always got an error:

ReferenceError: Error #1069: La property 0 cannot be found on Number 
  and there is no default value.
    at normal/unloadOverrides()[null/normal-generated.as:721]
    at normal/unload()[null/normal-generated.as:676]

Any idea on how to load/unload swf css in Flex4?

as seen on Stack Overflow - Search for 'Stack Overflow'
In Flex3, I could compile pure as3 code and use "embed" tags to load in images. This was done by Flex making a BitmapAsset class. I can still do this in Flex4. However, there was a trick to fakeout flex3 and use my own mx.core.BitmapAsset class to remove some of the extraneous stuff Flex's BitmapAsset… >>> More
