[flexcoders] Change LegendItem "fill" Color

[cwicky99]

I am trying to allow the user to select the color of the LegendItem. 
However, when I try and set the LegendItem "fill" style it doesn't
change in the UI.

I event tried:

legendItem.setStyle("fill", new SolidColor(0xFF00FF));
legendItem.invalidateDisplayList();

...but it has no effect.  I can call:

legendItem.setStyle("color", new SolidColor(0xFF00FF));

and the text associated with the LegendItem changes, but I can't seem
to change the fill color during runtime.

Any ideas or suggestions?
