How to manage orientation in landscape and portrait using fragment

I create one example in Android 3.0 and I use the fragment in it. when I change the mode landscape to portrait or viseversa it give me the error as following but when I comment the fragment calling part it works smoothly as per my changes. for this I create layout-land folder and put may xml file with changes.

does any one have a hint or solution or example for match with this?

this is my fragment:

 <fragment 
            class="com.Organisemee.fragment.TaskListFragment"
            android:id="@+id/tasklistfrag"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

And this is error:

Need to define a Fragment in XML Like This.

<RelativeLayout 
android:id="@+id/main_tasklist_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_toRightOf="@+id/main_viewmenu_layout"
android:layout_below="@+id/main_tasklist_outer">

 <fragment 
        class="com.Organisemee.fragment.TaskListFragment"
        android:id="@+id/tasklistfrag"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</RelativeLayout> 

To Call the Fragment put this code in java file

            Fragment f = listFragment();
            FragmentTransaction ListFragft = getFragmentManager().beginTransaction();
            ListFragft.replace(R.id.main_tasklist_layout, f);
            ListFragft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
            ListFragft.addToBackStack(null);
            ListFragft.commit();

This Works fine in change both orientation, landscape to portrait and vice versa.
