Hi Jeff,
have you already tried something like:
<class name="mypackage.sensors.IPMISensors" auto-complete="false"
verify-constructable="false">
<field name="redund" type="boolean">
<bind-xml name="redund" location="psSensors" node="attribute" />
</field>
<field name="powerSupplySensors"
type="mypackage.sensors.IPMIPowerSupplySensor"
required="false" direct="false" transient="false"
container="false" collection="collection">
<bind-xml name="psSensors" node="element" />
</field>
</class>
Regards
Ralf
