[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-2432) Collection Mapping via "property-ref" on non-pk-column crashes

Collection Mapping via "property-ref" on non-pk-column crashes -------------------------------------------------------------- Key: HHH-2432 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2432 Project: Hibernate3 Issue Type: Bug Components: core Environment: 3.2.2, Sybase DB Reporter: Stefan Krinkel Attachments: testcase.zip 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
