title: javafx2.2 making a scrollbar with transparent background
body: <p>I am trying to make a scrollpane with a scrollbar that has transparent (or at least solid)  background by styling it with css in javafx 2.2.3.</p>
  
  <pre><code>.scroll-pane .track{-fx-opacity: 0;}
  .scroll-pane .scroll-bar{-fx-base: transparent;}
  </code></pre>
  
  <p>Strangely, the code above makes scrollbar black. Giving -fx-base any value with alfa does that.</p>
  
  <p>Background-color has no efect at all...</p>
  
  <p>What am I missing?</p>
