title: Android ViewPager IllegalStateException: Can not perform this action after onSaveInstanceState
body: <p>I am using a ViewPager from the compatibility library. I get this exception quite often from the market reports.</p>
  
  <pre><code>java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState
  at android.support.v4.app.FragmentManagerImpl.checkStateLoss(FragmentManager.java:1242)
  at android.support.v4.app.FragmentManagerImpl.enqueueAction(FragmentManager.java:1253)
  at android.support.v4.app.BackStackRecord.commitInternal(BackStackRecord.java:535)
  at android.support.v4.app.BackStackRecord.commit(BackStackRecord.java:519)
  </code></pre>
  
  <p>Any ideas what might cause it?</p>
