Proxy / 1:1-Mapping

[Joerg Lensing]

Hi all,
up to now, I used "complete" object for references and all worked fine.
Now I try to use a proxy for a reference (version: rc4). The mapping is:
   <class-descriptor 
class="de.softcon.webcontrol.business.model.OrganisationPO" 
table="tpartner">
       <field-descriptor name="id" column="foid" jdbc-type="INTEGER" 
primarykey="true" autoincrement="true"/>
       <field-descriptor name="costUnitID" column="fcostunitid" 
jdbc-type="INTEGER"/>
       <field-descriptor name="mainBusiness" column="fbusiness" 
jdbc-type="VARCHAR"/>
       <reference-descriptor name="costUnit" 
class-ref="de.softcon.webcontrol.business.model.CostUnitPO" proxy="true">
           <foreignkey field-ref="costUnitID"/>
       </reference-descriptor>
   </class-descriptor>

   <class-descriptor 
class="de.softcon.webcontrol.business.model.CostUnitPO" table="tcostunit">
       <field-descriptor name="description" column="fdescription" 
jdbc-type="VARCHAR"/>
       <field-descriptor name="id" column="foid" jdbc-type="INTEGER" 
primarykey="true" autoincrement="true"/>
   </class-descriptor>

I get the following error-message:

[org.apache.ojb.broker.metadata.fieldaccess.PersistentFieldDefaultImpl]
