title: ActionBarSherlock setCustomView not working in Android 3.2
body: <p>I recently upgraded my application to use ActionBarSherlock 4.1. Since the upgrade users running the app on Honeycomb experiance a force close due to a null pointer exception when setting a custom view on the actionbar.</p>
  
  <p>I add a custom view containing two spinners to the actionbar this works on Android 4.0 &amp; 4.1 but is not working on 3.2.</p>
  
  <pre><code>            bar.setCustomView(R.layout.custom_action_bar);// spinners
              actionBarViewHolder= new CustomActionBarViewHolder();
              actionBarViewHolder.categorySpinner = (Spinner) findViewById(R.id.actionbar_catergory);
              actionBarViewHolder.sortBySpinner = (Spinner) findViewById(R.id.actionbar_sortby);
  </code></pre>
  
  <p>On Android 3.2 the spinners can not be found yet on 4.0 and 4.1 they views are found and anything runs smoothly. </p>
  
  <p>I have not tried the application on a 3.0 emulator but I image the problem persists.</p>
  
  <p>Any ideas what could be the problem?</p>
