title: Flex List selectedIndex is -1?
body: <p>I have a list in my flex application that has <code>requiresSelection = false</code> and <code>allowMultipleSelection = true</code>. I have run into a problem when I go to get the selected Index: it is returned as<code>-1</code>. I need to know what <code>Items</code> are selected in the list in order for my application to work. I have spent hours looking online and trying different methods to get this to work. Thanks in advance for any help.</p>
  
  <p>Full List Code:</p>
  
  <pre><code>&lt;s:List id="list1" x="10" y="35" width="100" height="400" allowMultipleSelection="true" click="list1Click(event)" 
  contentBackgroundColor="#696969" dataProvider="{list1Array}" itemRenderer="assets.ListSkinClass"/&gt;
  </code></pre>
