> Hi,
> when using the following example, Hibernate attempts to pull a "getTownId()" on an Integer!
> 2 Tables, Village and Councillor. Village has a comp. ID (TownId, VillageId), Councillor uses
> just the TownId-Part. To accomplish that, TOWN_ID is mapped twice (first in comp.key, second
> as "townCode"), to be able to do a 'property-ref'.
> When doing an ordinary "village.getCouncillors()" there's an IllegalArgumentException which
> roots to BasicPropertyAccessor.java:145
> 		public Object get(Object target) throws HibernateException {
> 			try {
> 				return method.invoke(target, null);
> 			}
> Here target is  (Integer) townId and method is "VillageId.getTownId".
>         <id name="id" type="integer">
>             <column name="COUNCILLOR_ID" />
>             <generator class="identity"/>
>         </id>
>         <property name="TOWN" type="integer" >
>             <column name="TOWN_ID" not-null="true" />
>         </property>
> ==============================================
>        <composite-id name="VillageId" class="Table1Id">
>             <key-property name="townId" type="integer">
>                 <column name="TOWN_ID" />
>             </key-property>
>             <key-property name="villageId" type="integer">
>                 <column name="VILLAGE_ID" />
>             </key-property>
>         </composite-id>   
> 	<property name="townCode" type="integer" insert="false" update="false">  
>             <column name="TOWN_ID" />
>         </property>
>         <bag name="councillors" outer-join="false" inverse="false"  >
>             <key property-ref="townCode">
>                 <column name="TOWN_ID" not-null="true" />
>             </key>
>             <one-to-many class="COUNCILLOR" />
>         </bag>
> Needless to say, it's a legacy database, so wildly changing tables is out of question for me, it has to
> work with hibernate.
> Thanks
