Try using DialogFragment and pass getChildFragmentManager() to your FragmentPagerAdapter's constructor.

DialogFragment:

public static class MyDialogFragment extends DialogFragment {

    private ViewPager viewPager;
    MySectionPagerAdapter mAdapter;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.m_layout, container);

        viewPager = (ViewPager) view.findViewById(R.id.viewpager);
        mAdapter = new MySectionPagerAdapter(getChildFragmentManager());
        viewPager.setAdapter(mAdapter);

        return view;
    }


}
