I have a polymorphic one-to-many association using table-per-hierarchy strategy. While it is working fine for persisting the association, I am unable to fetch an association of the base class.
<class name="Coverage" table="elig_Cov" discriminator-value="0">
<id name="id" column="elig_Cov_Id" type="java.lang.Long">
<generator class="seqhilo">
<param name="sequence">elig_Cov_Id_Sq</param>
<param name="max_lo">10</param>
</generator>
</id>
<discriminator column="CovStyle_Cd" type="integer"/>
<property name="useServicePlan"
column="UseSrvPlan" type="integer"/>
<many-to-one name="subscription" column="elig_Sub_Id"
cascade="save-update" lazy="false"/>
<subclass name="ServiceTierCoverage" discriminator-value="1">
<many-to-one name="servicePlan" column="csm_SrvPlan_Id"
lazy="true" cascade="none"/>
<bag name="serviceTierCoverageTs" inverse="true" lazy="false"
outer-join="true" cascade="all-delete-orphan"
collection-type="org.hibernate.usertype.PeriodOfExistenceType">
<key column="elig_Cov_Id"/>
<one-to-many class="ServiceTierCoverageT"/>
</bag>
</subclass>
<subclass name="VendorTierCoverage" discriminator-value="2">
<many-to-one name="vendorPlan" column="csm_VdrPlan_Id"
cascade="none" lazy="false"/>
<bag name="vendorTierCoverageTs" inverse="true"
lazy="false" outer-join="true" cascade="all-delete-orphan"
collection-type="org.hibernate.usertype.PeriodOfExistenceType">
<key column="elig_Cov_Id"/>
<one-to-many class="VendorTierCoverageT"/>
</bag>
</subclass>
</class>
Again, persistence is working fine, but calling subscription.getCoverages() returns an empty set. I'm even using "left join fetch sub.coverages" in my HQL and it is still not resolving this relationship properly.
Unfortunately, I ran into a bug with logging that has not yet been fixed in 3.0.5, so I can not turn on debug logging.
