[hibernate-issues] [Hibernate-JIRA] Created: (HHH-4939) Bidirectional OneToOne mapping with FK and composite PK sharing a column throws MappingException
Bidirectional OneToOne mapping with FK and composite PK sharing a column throws
MappingException
------------------------------------------------------------------------------------------------
Key: HHH-4939
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4939
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.3.2
Reporter: Chris Wilson
Attachments: HibernateAnnotationMappingOneToOneTest.java
A bidirectional one-to-one mapping, where the owning side's column is part of a
composite primary key, fails to configure, possibly because OneToOneType#getColumnSpan
returns zero instead of the actual number of columns used by the join.
When the foreign key column used is not also part of the primary key, or the composite
primary key contains only a single column, then the mapping doesn't fail.
