[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5176) property-ref doesn't work when property is inside join tags of destination mapping

From my understanding the 'column' attribute refers to the column of the local table that identifies the many-to-one relationship. 'property-ref' is used to specify the foreign-key of the destination table when we are joining on a column other than the primary key. The result that I'm looking for in this particular many-to-one relationship is something like:

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.
