title: ClassCastException in Eclpse 3.5 and 3.6 when in Graphical Layout with a SlidingDrawer
body: <p>Has anyone got the Graphical Layout working correctly in either Eclipse 3.5 or 3.6 when using a Sliding Drawer?  </p>
  
  <p>I keep getting the following error in both:</p>
  
  <p><strong><em>error!<br>
  ClassCastException: com.android.layoutlib.bridge.MockView cannot be cast to android.view.ViewGroup
  Exception details are logged in Window > Show View > Error LogThe following classes could not be found:
  - SlidingDrawer</strong></em>  </p>
  
  <p>I get this error with my code and any example code you can find around:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"
      android:background="#8CB69C"&gt;
  
      &lt;SlidingDrawer
          android:id="@+id/drawer"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:handle="@+id/handle"
          android:content="@+id/content"&gt;
  
      &lt;ImageView
          android:id="@id/drawerhandle"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:src="@drawable/drawerhandle"/&gt;
  
      &lt;/SlidingDrawer&gt;
  &lt;/FrameLayout&gt;  
  </code></pre>
  
  <p>When I run the app on a device it works fine without any problems so it's got to be a problem with either Android SDK 8, Eclipse 3.5 and 3.6 or my workspace, I've know idea yet.  If it works fine for others then it's got to be something local.  </p>
  
  <p>Here's the exception stack details:</p>
