findFragmentByTag always returns null

Where am i going wrong. I just want to check if the fragment with the given ProductId is already available in the BackStack;

If yes than dont add the new Fragment otherwise add the current fragment to the backstack.

public void showThisFragment(Fragment newFragment,int productId){
    FragmentManager fragmentManager = getSupportFragmentManager();
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    fragmentTransaction.replace(R.id.am_fragment_holder, newFragment);
    if(fragmentManager.findFragmentByTag(productId+"")==null){
        fragmentTransaction.addToBackStack(productId+"");
    }else{
        //TODO fragment already present
        //So dont add to the back stack
    }    
    fragmentTransaction.commit();
}

please help!

There is no tag added to replaced fragment. You should use three argument replace method. I did not test it so tell me if I am right.

fragmentTransaction.replace(R.id.am_fragment_holder, newFragment, String.valueOf(productId));
