xml - android include tag - invalid layout reference

Question

I'm having a problem including a different layout through the include tag in the android layout xml file. When specifing the layout reference ( @layout/... ), i'm getting a InflateException in the Eclipse ADT with the following error: InflateException: You must specifiy a valid layout reference. The layout ID @layout/func_edit_simple_calculator_toolbox is not valid.

the reference should be valid, as I've selected it from the the list of my other layouts and didnt type it in. I'm using android sdk v2.1

these are the layout files

func_edit_simple_calculator_toolbox.xml

<?xml version="1.0" encoding="utf-8"?>
<TableLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_height="wrap_content" android:layout_width="wrap_content">

<TableRow android:id="@+id/TableRow01" android:layout_width="wrap_content"android:layout_height="wrap_content">
<Button android:id="@+id/Button01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="1"></Button>
<Button android:id="@+id/Button02" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="2"></Button>
<Button android:id="@+id/Button03" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="3"></Button>
<Button android:id="@+id/Button04" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="+"></Button>
</TableRow>
<TableRow android:id="@+id/TableRow02" android:layout_width="wrap_content" android:layout_height="wrap_content">
<Button android:id="@+id/Button05" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="4"></Button>
<Button android:id="@+id/Button06" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="5"></Button>
<Button android:id="@+id/Button07" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="6"></Button>
<Button android:id="@+id/Button08" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="-"></Button>
</TableRow>
</TableLayout>

function_editor_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >

<com.calculoid.FunctionView android:id="@+id/function_view" android:layout_width="fill_parent" android:layout_height="fill_parent"/>

<include android:id="@+id/include01" android:layout_width="wrap_content" android:layout_height="wrap_content" layout="@layout/func_edit_simple_calculator_toolbox"></include>
</LinearLayout>

Does any one know what could be the problem?

thanks in advance

If anyone stumbles upon this thread looking for this error:

Caused by: android.view.InflateException: You must specifiy a layout in the include tag: <include layout="@layout/layoutID" />

Make sure you do:

<include layout="@layout/your_layout" />

and not:

<include android:layout="@layout/your_layout" />

layout should not have android: in front of it.
