title: Actionbar scherlock is not refreshed when the orientation is changed
body: <p>I use Sherlock action bar in my application. I used "ifRoom|withText" feature  in my menu. If I test my code in portrait mode, I can see only icon and if I  rotate orientation to landscape, still I see only icon. On the other hand, if I run with landscape, I can see text and icon on portrait and landscape. This means that When the screen is rotated, action bar is not refreshed. How can I fix?</p>
  
  <p>In menu, I have</p>
  
  <pre><code>    android:showAsAction="ifRoom|withText"
  </code></pre>
  
  <p>Also I used this line in my manifest file to fixed </p>
  
  <pre><code>    android:configChanges="keyboardHidden|orientation|screenSize"
  </code></pre>
  
  <p>but it didn't work. And I run my code android 2.3</p>
  
  <p>Also I used fragment in my activity, </p>
  
  <pre><code>        FragmentManager fm = getSupportFragmentManager();
      ft = fm.beginTransaction();
  
      mFragment1 = fm.findFragmentByTag("f1");
  
      if (mFragment1 == null) {
  
          mFragment1 = new MenuFragment();
          ft.add(mFragment1, "f1");
  
      }
  
      ft.commit();
  </code></pre>
