Eu tinha declarado frammentAtividade como abaixo:

    mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);
    mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);
    mTabHost.addTab(mTabHost.newTabSpec("basic").setIndicator("Basic",getResources().getDrawable(R.drawable.ic_launcher)),BasicProductFragment.class, null);
    mTabHost.addTab(mTabHost.newTabSpec("taxes").setIndicator("Taxes",getResources().getDrawable(R.drawable.ic_launcher)),TaxesProductFragment.class, null);
    mTabHost.addTab(mTabHost.newTabSpec("price").setIndicator("Price",getResources().getDrawable(R.drawable.ic_launcher)),PriceProductFragment.class, null);
    mTabHost.addTab(mTabHost.newTabSpec("stock").setIndicator("Stock",getResources().getDrawable(R.drawable.ic_launcher)),StockProductFragment.class, null);
