Hi *,

I have a simple object model composed from three classes with their relationship as described above by mapping file. One of them is the superclass for the other two, and I have defined a filter for it. If filter is activated and try to retrieve an instance of subclass, generated SQL is invalid and an exception is thrown (see logs below).

Hibernate: 3.2.3
DB: MySQL 5.0.27, MS-SQL 2000, ...

Mappings:
<hibernate-mapping>
<class name="test.model.Entity" table="entity">
<id name="id" column="id" type="long">
<generator class="identity" />
</id>

<property name="siteId" type="string">
<column name="siteId" />
</property>

<joined-subclass name="test.model.User" table="user">
<key column="id" />
<property name="FirstName" type="string">
<column name="firstName" />
</property>
<property name="LastName" type="string">
<column name="lastName" />
</property>
<one-to-one name="Account" property-ref="User" cascade="delete" />
</joined-subclass>

<joined-subclass name="test.model.Account" table="account">
<key column="id" />
<property name="name" type="string">
<column name="name" />
</property>

<many-to-one name="User" column="user_id" class="test.model.User" unique="true" not-null="true" />
</joined-subclass>
<filter name="siteIdFilter" condition="siteId=:siteId" />
</class>
<filter-def name="siteIdFilter">
<filter-param name="siteId" type="string" />
</filter-def>
</hibernate-mapping>

Code:
Session session = HibernateUtils.currentSession();
session.enableFilter("siteIdFilter").setParameter("siteId", "opp");
User user = (User) session.get(User.class, new Long(3));
session.close();

Any help would be appreciated.
