when i try to write the observer for the `checkout_type_onepage_save_order` event like following

```
<events>
    <checkout_type_onepage_save_order>
        <observers>
            <Appeal_Consignor_Model_Observer>
                <type>singleton</type>
                <class>consignor/observer</class>
                <method>savedata</method>
            </Appeal_Consignor_Model_Observer>
        </observers>
    </checkout_type_onepage_save_order>
</events>

```

above code i tried in `frontend` as well as `global`.

Even i tried following as well.

```
<events>
    <checkout_type_onepage_save_order>
        <observers>
            <Appeal_Consignor_Model_Observer>
                <type>singleton</type>
                <class>Appeal_Consignor_Model_Observer</class>
                            <method>savedata</method>
            </Appeal_Consignor_Model_Observer>
        </observers>
    </checkout_type_onepage_save_order>
</events>

```

yet the following error is coming. I cleared cache 1000 times, deleted var cache folder file manually as well.
