Hi,

I am new to hibernate. My natural-id is a combination of a column from a component and a many-to-one field.


<component name="nameValuePair"
class="xxx.sss.NameValuePair">
<property name="name" type="string">
<column name="nvname" not-null="true" length="255"/>
</property>
<property name="value" type="string">
<column name="nvvalue" not-null="false" length="255"/>
</property>
</component>


<many-to-one name="field"
class="xxx.yyy.Field" cascade="none"
fetch="join">
<column name="field_id" />
</many-to-one>

How do i map the natural-id? Following does not work.

<natural-id>
<property name="field"/>
<property name="nvname" not-null="true" length="255"/>
</natural-id>


thank you.
