Unfortunately, styles don't work with binding. Here's another approach:
// inside SystemMessage.mxml
<mx:Script>
<![CDATA[
[Bindable]
public var message:String;
public function set textColor(c:Number):Void
{
LblSystemMessage.setStyle("color", c);
}
]]>
<mx:Script>
Then, from the outside you do:
this.TheSystemMessageDialog.textColor = 0x333333;
The implicit setter function inside SystemMessage.mxml looks like a public
member to the outside world but allows you to encapsulate functionality. Note,
the color value is typed as Number.
