ViewPager: Recursive entry to executePendingTransactions

New version of Support Library v4 (or Android 4.2, ofcourse) resolve this problem much simply. For do this, simply do constructor of your custom FragmentPagerAdapter like this:

public CustomFragmentPagerAdapter(android.support.v4.app.Fragment fragment)
{
    super(fragment.getChildFragmentManager());

    // write your code here
}

This work because new Android version approve using nested Fragments
