Help could some please help me with property-ref?

my map looks like this

<class name="KFolder" table="nodes">
<id name="nodeId" type="string" column="node_id" length="180"></id>
<property name="nodeName" column="node_name" type="string" length="241" not-null="true"/>
<property name="status" column="status" type="string" length="20"/>
<one-to-one name="kfnm" class="KFolderNodeMap" property-ref="linkNodeId"/>
</class>
<class name="KFolderNodeMap" table="node_map">
<id name="linkNodeId" type="string" column="link_node_id" length="180"></id>
<property name="numObjects" column="num_objects" type="int" length="11"/>
<property name="seqNum" column="seq_num" type="int" length="11"/>
</class>



When I run a test driver I get this

(cfg.Configuration 879 ) processing collection mappings
(cfg.Configuration 888 ) processing association property refer
ences
Exception in thread "main" org.hibernate.MappingException: property-ref not foun

I can reproduce the problem in the example "inventory" that comes with hibernate by adding a property-ref clause in the product map


<one-to-one name="supplier"
class="Supplier"
property-ref="id"
cascade="save-update"/>


would someone please be kind enough to point out my error.


thanks in adavance.

It makes no sense to use property-ref on the id, that is the default behaviour of a one-to-one already. Just drop the property-ref. And please read http://www.hibernate.org/hib_docs/v3/re ... n-onetoone
