    • Workaround Description:
      Hide

      this is caused by the wrong alias generation when retrieving date from the ResultSet, Column.getAlias(Dialect) method will cut off the rest of letters after the first non-letter character, so map your collection column name to something else may resolve this problem
      or if you're working with a legacy system which you can not change the column name, then there are 2 options
      1. use another inheritance strategy
      2. change the order of property mapped in hbm (haven't test with annotations yet)

      Description

      see http://opensource.atlassian.com/projects/hibernate/browse/HHH-4825
      this issue also exist in annotations, see JBPAPP-3560

      Following mapping fails:

      <hibernate-mapping default-access="property" package="case419703">

      <class abstract="false" dynamic-insert="true" dynamic-update="true" name="TestB"
      table="TEST_B">
      <composite-id class="case419703.key.FrameworkKeyCustID"
      name="frameworkKey">
      <key-property column="NR_RZBK" name="frameworkCustId"/>
      <key-property column="TXT_OID" name="frameworkOid"/>
      </composite-id>
      <version column="NR_VERSION" name="frameworkVersion"/>

      <set cascade="persist, merge, save-update" inverse="true" lazy="true" name="testC">
      <key>
      <column name="NR_RZBK"/>
      <column name="TXT_OID_TESTB"/>
      </key>
      <one-to-many class="TestC"/>
      </set>
      </class>

      <class abstract="true" dynamic-insert="true" dynamic-update="true" name="AbstractTestC"
      table="notable">
      <composite-id class="case419703.key.FrameworkKeyCustID"
      name="frameworkKey">
      <key-property column="NR_RZBK" name="frameworkCustId"/>
      <key-property column="TXT_OID" name="frameworkOid"/>
      </composite-id>
      <version column="NR_VERSION" name="frameworkVersion"/>

      <union-subclass dynamic-insert="true" dynamic-update="true" name="case419703.TestC"
      table="TEST_C">
      <property column="PID" name="pid" update="false"/>
      <property column="TXT_OID_TESTB" name="fkReverseTestB"/>
      <many-to-one cascade="persist, merge, save-update" class="case419703.TestB"
      fetch="select" insert="false" lazy="no-proxy" name="reverseTestB"
      update="false" >
      <column name="NR_RZBK" />
      <column name="TXT_OID_TESTB" />
      <!-- formula>'TXT_OID_TESTB'</formula-->
      </many-to-one>
      </union-subclass>
      </class>
      </hibernate-mapping>

      however changing to

      <many-to-one cascade="persist, merge, save-update" class="case419703.TestB"
      fetch="select" insert="false" lazy="no-proxy" name="reverseTestB"
      update="false" >
      <column name="NR_RZBK" />
      <column name="TXT_OID_TESTB" />
      <!-- formula>'TXT_OID_TESTB'</formula-->
      </many-to-one>
      <property column="PID" name="pid" update="false"/>
      <property column="TXT_OID_TESTB" name="fkReverseTestB"/>
      works.

      Something is wrong with th algo.
      See attached testcase.
