I'm getting a "org.hibernate.MappingException: duplicate property mapping: _addressesBackref" error.
I have 2 classes (Freelancer and Author) mapped to the same table (people) with a where property on the class. Each class has a address bag which when commented out on one or the other classes makes the problem dissapear.
Hibernate version: 3.0.5
Mapping documents:
Code:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="domain.Freelancer" table="people" where="type='freelancer'">
<id name="personId" column="person_id">
<generator class="native" />
</id>
<!-- yaddaa yadda yadda-->
<bag name="addresses" order-by="is_primary desc" cascade="all-delete-orphan">
<key column="person_id" not-null="true" />
<one-to-many class="org.aafp.tracker.domain.Address" />
</bag>
</class>
</hibernate-mapping>
