[hibernate-issues] [Hibernate-JIRA] Created: (HHH-5176) property-ref doesn't work when property is inside join tags of destination mapping
property-ref doesn't work when property is inside join tags of destination mapping
----------------------------------------------------------------------------------
Key: HHH-5176
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5176
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.5.0-Final
Environment: mapping
Reporter: Stephen Visser
My legacy system requires that I have a join in the mappings to fully specify.
Here is the mapping of the entity.
{quote}
<hibernate-mapping>
<class name="Student" table="PERSONS"
lazy="false">
<id name="personID" column="PERSON_ID"/>
<property name="lastName" column="LEGAL_SURNAME" />
<property name="firstName" column="LEGAL_FIRST_NAME" />
<property name="birthDate" column="DATE_OF_BIRTH" />
<join table="STUDENTS">
<key column="PERSON_ID"/>
<property name="studentID" column="STUDENT_ID"
unique="true" />
</join>
</class>
</hibernate-mapping>
{quote}
However, when I reference the entity in another mapping:
{code}
<hibernate-mapping>
<class name="Enrolment" table="COURSE_ENROLLMENTS"
lazy="false">
<id name="enrolmentID" column="course_enrollment_id" />
<many-to-one name="student" column="student_id"
class="Student" lazy="false" property-ref="studentID"/>
</class>
</hibernate-mapping>
{code}
The studentID property in the Student mapping is assumed to be in the PERSONS table (when
in fact it is in the STUDENTS table since it's inside the join tags). This results in
the alias of the PERSONS table being prepended to the STUDENT_ID column.
When using the property-ref attribute, it should be determined if the referenced property
is inside any join tags. If it is, the correct table alias should be inferred.
