title: onCreateOptionsMenu not triggered in fragment
body: <p>I encounter an issue with one of my fragments which does not trigger at all onCreateOptionsMenu() unlike my other fragments. There is no exception neither or any particular trace and I use the setHasOptionsMenu(true) method.</p>
  
  <pre><code>package fr.test.test.fragment;
  
  import android.app.ActionBar;
  import android.support.v4.app.Fragment;
  import android.os.Bundle;
  import android.view.LayoutInflater;
  import android.view.Menu;
  import android.view.MenuInflater;
  import android.view.View;
  import android.view.ViewGroup;
  
  import fr.test.test.MainActivity;
  import fr.test.test.listener.FragmentTabListener;
  import fr.test.test.R;
  
  public class TestFragment extends Fragment {
  
      private ActionBar.Tab Tab1, Tab2;
      private Fragment fragmentTab1;
      private Fragment fragmentTab2;
      private ActionBar actionBar;
  
      public TestFragment() {
  
          fragmentTab1 = new Fragment1();
          fragmentTab2 = new Fragment2();
      }
  
      @Override
      public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
  
          View rootView = inflater.inflate(R.layout.fragment_messages, container, false);
          setHasOptionsMenu(true);
  
          actionBar = getActivity().getActionBar();
          actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
  
          Tab1 = actionBar.newTab().setText(R.string.title_fragment1);
          Tab2 = actionBar.newTab().setText(R.string.title_fragment2);
  
          Tab1.setTabListener(new FragmentTabListener(getActivity(), fragmentTab1));
          Tab2.setTabListener(new FragmentTabListener(getActivity(), fragmentTab2));
  
          actionBar.removeAllTabs();
          actionBar.addTab(Tab1);
          actionBar.addTab(Tab2);
  
          return rootView;
      }
  
      @Override
      public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
          System.out.println("onCreateOptionsMenu TRIGGER ME PLZ :( ");
          inflater.inflate(R.menu.global, menu);
      }
  }
  </code></pre>
  
  <p>The problem does not come from my menu because my other fragments triggers this event, that's why I do not understand a thing on this case. I use exactly the same logic but with the standart navigation from the ActionBar instead of tabs. Any ideas ?</p>
  
  <p>Thanks for watching,</p>
  
  <p>Regards.</p>
