binding fails if both attribute and element are used, ordered="false" and there is an inheritance.

This binding fails:

<binding forwards="false" value-style="attribute">
<mapping name="TestClass" class="com.TestClass"
extends="com.TestBase" ordered="false">
<value style="element" name="paramC" field="paramC" usage="optional"/>
<value name="paramD" field="paramD" />
<structure name="TestBase" map-as="com.TestBase"/>
</mapping>

<mapping abstract="true" class="com.TestBase" ordered="false">
<value style="element" name="paramA" field="paramA" usage="optional"/>
<value name="paramB" field="paramB" usage="optional"/>
</mapping>
</binding>
