title: Dragging in spark List does not work in Flex mobile app? Test case and screenshot attached
body: <p>I would like to reorder items of a List in a Flex mobile app by dragging them around with a finger.</p>
  
  <p>As a first step I have copied the example from Adobe document <a href="http://help.adobe.com/en_US/flex/using/WS2db454920e96a9e51e63e3d11c0bf69084-7cfd.html" rel="nofollow noreferrer">Using drag-and-drop with list-based controls</a> - but while their example works fine as web application, nothing happens in the mobile app below:</p>
  
  <p><img src="https://i.stack.imgur.com/YmyUc.png" alt="screenshot"></p>
  
  <p>Why doesn't it work (like is some skin missing in the mobile theme?)</p>
  
  <p>Is there a way to make it work (at least reordering items in a mobile List)?</p>
  
  <p>Below is the simple test code I've tried - just put it into a new blank (i.e. without a nav. bar) Flex mobile project in Flash Builder:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
                 xmlns:s="library://ns.adobe.com/flex/spark" 
                 applicationDPI="160"
                 creationComplete="initApp()"&gt;
  
      &lt;s:layout&gt;
          &lt;s:VerticalLayout/&gt;
      &lt;/s:layout&gt;
  
      &lt;fx:Script&gt;
          &lt;![CDATA[
              import mx.collections.ArrayCollection;
  
              private function initApp():void {
                  srclist.dataProvider = 
                      new ArrayCollection(['Reading', 'Television', 'Movies']);
                  destlist.dataProvider = new ArrayCollection([]);
              }
          ]]&gt;
      &lt;/fx:Script&gt;
  
      &lt;s:HGroup&gt;
          &lt;s:VGroup&gt;
              &lt;s:Label text="Available Activities"/&gt;
              &lt;s:List id="srclist" 
                      allowMultipleSelection="true"
                      dragEnabled="true"
                      dragMoveEnabled="true"/&gt;
          &lt;/s:VGroup&gt;
  
          &lt;s:VGroup&gt;
              &lt;s:Label text="Activities I Like"/&gt;
              &lt;s:List id="destlist" 
                      dropEnabled="true"/&gt;
          &lt;/s:VGroup&gt;
      &lt;/s:HGroup&gt;
  
      &lt;s:Button id="b1" 
                label="Reset"
                click="initApp();"/&gt;  
  
  &lt;/s:Application&gt;
