[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-2320) Regression: optional properties under a <join> tag no longer update properly

Regression: optional properties under a <join> tag no longer update properly ---------------------------------------------------------------------------- Key: HHH-2320 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2320 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.0.cr4, 3.2.0.cr5, 3.2.0.ga, 3.2.1 Environment: hibernate 3.2.0.cr4 through 3.2.1.ga hsql 1.8.0.7 and Oracle 9i Reporter: Chris Jones Assignee: Gail Badner Fix For: 3.2.6, 3.3 Attachments: HHH-2320-test.patch, HHH-2320.patch, OptionalJoinTest.jar This was specifically introduced with the revision 10217 changes on the 3.2 branch in src/org/hibernate/persister/entity/AbstractEntityPersister.java Given the following setup: <class name="Thing"> <id .../> <join table="JOIN_TABLE" optional="true"> <key column="THING_ID" not-null="true"/> <property name="joinedProperty" column="JOINED_PROPERTY"/> </join> </class> scenario: Thing thing1 = new Thing(); thing1.setJoinedProperty("thing1"); save(thing1); // a record in the JOIN_TABLE is created properly and updates on the property can occur Thing thing2 = new Thing(); thing2.setJoinedProperty(null); save(thing2); // no record in JOIN_TABLE is created thing2.setJoinedProperty("thing2"); save(thing2); // in revision 10216, hibernate correctly runs an INSERT to create a JOIN_TABLE record with the value "thing2" // in revision 10217, hibernate incorrectly runs an UPDATE to try and update a non-existant record in the JOIN_TABLE with the thing2 id It looks like the expectation.verifyOutcome() method should be throwing a StaleStateException if the attempted update effects 0 rows. I will try and get an official hibernate testcase going and possibly a patch, but I wanted to enter this now in case there is something I'm missing that makes this change in functionality intentional.
