ActionBarSherlock setCustomView not working in Android 3.2

I recently upgraded my application to use ActionBarSherlock 4.1. Since the upgrade users running the app on Honeycomb experiance a force close due to a null pointer exception when setting a custom view on the actionbar. I add a custom view containing two spinners to the actionbar this works on Android 4.0 & 4.1 but is not working on 3.2. ``` bar.setCustomView(R.layout.custom_action_bar);// spinners actionBarViewHolder= new CustomActionBarViewHolder(); actionBarViewHolder.categorySpinner = (Spinner) findViewById(R.id.actionbar_catergory); actionBarViewHolder.sortBySpinner = (Spinner) findViewById(R.id.actionbar_sortby); ``` On Android 3.2 the spinners can not be found yet on 4.0 and 4.1 they views are found and anything runs smoothly. I have not tried the application on a 3.0 emulator but I image the problem persists. Any ideas what could be the problem? ``` <LinearLayout android:id="@+id/linearLayout1" android:layout_width="wrap_content" android:layout_height="match_parent" android:gravity="center_vertical|center_horizontal" android:layout_weight="0.5"> <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Category:" /> <Spinner android:id="@+id/actionbar_catergory" android:layout_width="wrap_content" android:layout_height="wrap_content" android:entries="@array/actionbar_spinner_catergory" android:background="@drawable/spinner_background" /> </LinearLayout> <LinearLayout android:id="@+id/linearLayout1" android:layout_width="wrap_content" android:layout_height="match_parent" android:gravity="center_vertical|center_horizontal" android:layout_weight="0.5"> <TextView android:id="@+id/textView2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Sort By:" /> <Spinner android:id="@+id/actionbar_sortby" android:layout_width="wrap_content" android:layout_height="wrap_content" android:entries="@array/actionbar_spinner_sortby" android:background="@drawable/spinner_background" /> </LinearLayout> ```
