[flexcoders] how to let setting different style be handled by different subcomponents?

[Rich Rodecker]

I have a component which extends Canvas.  I am using a custom borderSkin on
the Canvas and that works out fine.  Within that canvas I have a TextArea.
 I'm trying to figure out how to make calls to
myComp.setStyle('backgroundColor', 0) pass through to the TextArea, so that
the TextArea's background is actually being set, and not the borderSkin.
 Can that be done?
