android:configChanges="orientation" does not work with fragments

I am just trying to adapt some of my applications for HoneyComb.

The issue iI am facing is the destruction of my activity on orientation change (landscape/portrait)

When I was using a classic activity, I wrote in the manifest:

But now, all these lines aren't working anymore!

Is there a workaround for that?

My code:

    <activity android:name=".TwitterActivity" android:label="@string/app_name"
        android:configChanges="keyboardHidden|orientation" />

    <activity android:name=".TwitterActivity$AppListFragment"
    android:configChanges="keyboardHidden|orientation"  />
