title: flex 4 textinput skin background color
body: <p>I'm trying to change the background color on a textinput component in flex 4. I've been able to change some of the appearance by messing with the canned code flash builder generates for the sparkskin but for some reason, background does nothing.</p>
  
  <p>I'm just trying to make the background black. I changed the background color but it's not working:</p>
  
  <pre><code>&lt;!-- fill --&gt;
  &lt;!--- Defines the appearance of the TextInput component's background. --&gt;
  &lt;s:Rect id="background" left="1" right="1" top="1" bottom="1"&gt;
      &lt;s:fill&gt;
          &lt;!--- @private Defines the background fill color. --&gt;
          &lt;s:SolidColor id="bgFill" color="0x000000" /&gt;
      &lt;/s:fill&gt;
  &lt;/s:Rect&gt;
  </code></pre>
