OneToOneSecondPass Metadata is mistakenly interpreted ----------------------------------------------------- Key: HHH-4851 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4851 Project: Hibernate Core Issue Type: Bug Components: annotations Affects Versions: 3.5.0-Beta-3 Reporter: Claude Houle Attachments: hibernate-annotation-3.4.0.GA_3.4.0.1.GA.patch, unit-test.zip Original Estimate: 30 minutes Remaining Estimate: 30 minutes I've been tracking an issue that has been causing us some trouble regarding annotation-based hibernate mappings. The exception occurs at run-time only: /org.hibernate.PropertyValueException: not-null property references a null or transient value ... / At first I believed we had an issue with our entity mapping was faulty and went to try and figure it out... However, I came accross several examples on the wide internet and showed that my mapping seems correct. Furthermore, I had some other entities mapped in a similar fashion that did not cause any issue... How could that be? I traced the Hibernate code to a class named org.hibernate.cfg.OneToOneSecondPass (Hibernate Annotations 3.4.0.GA for those interested to look at the code) up to line 147: ... Iterator it = otherSide.getJoinIterator(); Join otherSideJoin = null; while ( it.hasNext() ) { otherSideJoin = (Join) it.next(); if ( otherSideJoin.containsProperty( otherSideProperty ) ) { break; } } if ( otherSideJoin != null ) { ... } ... If you look closely, it seems that if there are JOINs but none contains the otherSideProperty, the variable otherSideJoin will not be null and will contains the last joins of the iterator even if it is not valid. The patched-up code would look like: ... Iterator it = otherSide.getJoinIterator(); Join otherSideJoin = null; while ( it.hasNext() ) { Join otherSideJoinValue = (Join) it.next(); if ( otherSideJoinValue.containsProperty( otherSideProperty ) ) { otherSideJoin = otherSideJoinValue; break; } } if ( otherSideJoin != null ) { ... } ...
