Transform bug fixes
http://bugs.adobe.com/jira/browse/SDK-22046 - Can't set matrix3D property on Transform
Player declares matrix3D setter with * return type. So mx.geom.Transform override must also use *. Note that once the Player is updated with void, this will need to be changed to void.
http://bugs.adobe.com/jira/browse/SDK-22146 - AlphaMultiplier and AlphaOffset in color transformation are ignored in MXML Graphics
Changed the behavior of alpha and ColorTransform for GraphicElement to match the behavior of DisplayObject.
- ColorTransform.alphaMultiplier and alpha are equivalent and are kept in sync.
- ColorTransform.alphaOffset is still applied even if alpha is set.
Implementation details:
- mx.geom.Transform sets the colorTransformExplicitlySet flag whenever the colorTransform setter is called
- GraphicElement alpha setter clears the colorTransformExplicitlySet flag whenever it is called
- Setting GraphicElement.transform will update the alpha property with ColorTransform.alphaMultiplier if a colorTransform was explicitly set
- Setting the colorTransform on a mx.geom.Transform that is assigned to a GraphicElement, calls setColorTransform, which updates the alpha property with ColorTransform.alphaMultiplier.
- In commitProperties, the displayObject.alpha is updated only if there is no transform or if colorTransformExplicitlySet is false.
QE Notes: Need tests for combo of alpha and colorTransform alpha props
Doc Notes: None

Answer 1

This bug figures out also when creating a custom spark ComboBox, then trying to programatically update the userProposedSelectedIndex property. The proposed selected index is selected, but does not apply the same skin as when mouse is on rollover or item is selected due to up and down keys.
The issue seems like updating the status of the item renderer to rollover or selected to get the same skin applied.
Please could you attach DropDow nList.as that you edited ?
Thank you so much.
