Saya menggunakan fragmen, saat saya membuat instance fragmen untuk pertama kali. tapi kedua kalinya saya mendapat pengecualian ini. Saya tidak dapat menemukan baris di mana saya mendapatkan kesalahan?

Inilah yang saya lakukan ketika saya mengklik elemen dari fragmen daftar saya.
// If we are not currently showing a fragment for the new
// position, we need to create and install a new one.
RouteSearchFragment df = RouteSearchFragment.newInstance(index);
// Execute a transaction, replacing any existing fragment
// with this one inside the frame.
FragmentTransaction ft = fragmentManager.beginTransaction();
ft.replace(R.id.details_full, df);
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
ft.commit();
Pertama kali ok, saya klik elemen2 dari daftar, juga ok; tetapi ketika saya kembali ke elemen1 saya mendapat bug ini.
Terimakasih semuanya!
