MicroPlotChart - using colors does not correctly change SolidFill of plots - all plots have a black fill.

What steps will reproduce the problem?
1. Create a MicroPlotChart using a colors array
<microcharts:MicroPlotChart width="200" height="40" showDataTips="true" 
dataField="val" backgroundColor="#DDDDDD" backgroundStroke="#888888" 
colors="[0xFFFFFF, 0xFFFFFF, 0, 0xFF0000, 0]" dataProvider="{dp}" 
negative="false" radius="10" />

2. Note that all of the circles show up with black fills, instead of 2 
white, 1 red, 2 black.

Analysis:

In createPlots() in MicroPlotChart.as, the line for using the colors array 
is correctly being called, based on the flex debugger:

  if (colors != null) {
    plot.fill = new SolidFill(useColor(i));
  }

The Degrapha asdocs for SolidFill say that the first arg should be an 
Object specifying a color value (unit or string).

However, the useColor() method in BaseMicroChart.as is returning a 
IGraphicsFill object, not a color value:
  protected function useColor(indexIteration:Number):IGraphicsFill

The Degrapha code is just treating an unknown type of object input as 
black, so everything shows up that way.

Fix: Use the fill returned from useColor() instead of creating a SolidFill.
  if (colors != null) {
    plot.fill = useColor(i);
    //plot.fill = new SolidFill(useColor(i));
  } 

The attached image shows that the different colors now appear.

What version of the product are you using? On what operating system?
