title: Fragment already active - When trying to setArguments
body: <p>I am using the example give in the below link</p>
  
  <p><a href="http://android-er.blogspot.in/2013/04/handle-onlistitemclick-of-listfragment.html">http://android-er.blogspot.in/2013/04/handle-onlistitemclick-of-listfragment.html</a></p>
  
  <p>Here i have two classes one extending List Fragment and other extending Fragment.
  Now i am passing object to detailfragment in this way :</p>
  
  <p>*<em>from ListFragment *</em></p>
  
  <pre><code>@Override
      public void onListItemClick(ListView l, View v, int position, long id) {
          Detailfragment detailFragment = (Detailfragment)getFragmentManager().findFragmentById(detailFragmentID);
  
          Bundle bundle = new Bundle();
          bundle.putSerializable(BUNDLE_KEY, obj);// passing this object
  
          detailFragment.setArguments(bundle);
          detailFragment.setUpLayout();// update the UI
  } 
  </code></pre>
  
  <p>Now in the <strong>Fragment</strong> class i receive it,basic goal is to update the UI of the fragment based on the item selected in the list fragment, thats the reason i am sending the object</p>
  
  <pre><code>Bundle b = getArguments();
  b.getSerializable(BUNDLE_KEY);
  </code></pre>
  
  <p>Now on item selected it says "Fragment already active".</p>
  
  <p>What is the issue here? what am i doing wrong?</p>
