[flexcoders] SolidColor can have bindabale color and GradientEntry can not ?

[alex]

I have a ColumnChart with couple of CoulumnSeries
I'm making one ColumnSeries with bindable SolidColor and it works fine
the second one with LinearGradient won't read  the same bindable 
values .... How come ?

<mx:ColumnSeries>
  <mx:fill>
        <mx:SolidColor 
color="{model.colorTheme.getItemAt(1).toString()}" 
                                                />
  </mx:fill>
</mx:ColumnSeries>



<mx:ColumnSeries 
  <mx:fill>
      <mx:LinearGradient  angle="90">
             <mx:entries>
                 <mx:Array>
                                    <mx:GradientEntry 
color="{model.colorTheme.getItemAt(0).toString()}"
                                        ratio="0"             
alpha="1"  />

                                    <mx:GradientEntry 
color="{model.colorTheme.getItemAt(1).toString()}"
                                        ratio="0.9" 
                                        alpha="0.5" />
                 </mx:Array>
             </mx:entries>
       </mx:LinearGradient> 
    </mx:fill> 
</mx:ColumnSeries>
