Hi does any body knows when natural-id's attribute muttable="true" is required in hibernate mapping bcz i got the error which is mentioned below while saving transient object(Property object) with detached object(estateAgent object)
service().update(estateAgent);
and Property.hbm.xml is

<natural-id>
<many-to-one name="estateAgent" class="EstateAgent" cascade="none" column="estateAgent"/>
<property name="propertyAddress" column="PropertyAddress" not-null="true"/>
<property name="postcode" column="PostCode" not-null="true"/>
</natural-id>
and estateAgent.hbm.xml
is
<set name="propertySet" inverse="true" cascade="all-delete-orphan" lazy="true">
<!-- the foreign key column in the table for property that refers to THIS estateAgent object -->
<key column="estateAgent"/>
<!-- the class contained in this set -->
<one-to-many class="Property"/>
</set>
