When I try to delete a subclass entity, the resulting SQL is bad; it appears to be assuming an alias is being used when it isn't.

Mapping file (partial):
<hibernate-mapping>
    <class name="com.wotif.jaguar.domain.Comment"
        table="COMMENTS" dynamic-update="false" dynamic-insert="false"
        select-before-update="false" optimistic-lock="version"
        discriminator-value="null" >
...
        <subclass
            name="com.wotif.jaguar.domain.property.PropertyComment"
            dynamic-update="false"
            dynamic-insert="false"
            discriminator-value="0"
        >
...
    </class>
</hibernate-mapping>

19/04/2005 14:25:20 org.hibernate.hql.ast.QueryTranslatorImpl generate FINE: SQL: delete from COMMENTS where propertyco0_.CommentType=0


Under Hibernate 2.1.6, the generated SQL was:

delete from COMMENTS propertyco0_ where propertyco0_.CommentType = 0


My guess: the change to remove aliasing for update/deletes caused this to break.
