using @SecondaryTable with optional=true not handled for joined subclasses (@Inheritance(strategy = InheritanceType.JOINED) --------------------------------------------------------------------------------------------------------------------------- Key: HHH-6381 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6381 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.6.5, 4.0.0.Beta2 Environment: linux, jdk 1.6, hibernate latest from master, oracle 11gr2 Reporter: David Mansfield Assignee: Hardy Ferentschik When using a _@SecondaryTable(name="xx")_, set to optional using _(a)org.hibernate.annotations.Table(name="xx",optional=true)_ the documentation states that the secondary table row will only be populated if any one of the properties mapped to the secondary table are not-null. However, this does not work with joined subclasses using the _JoinedSubclassEntityPersister_. This is because, internally, the boolean which controls "outer joinability" (called _isNullableTable_) always returns _false_. A fix has been tested which will be put into a github pull request. The fix implements _isNullableTable_ to honor the optional flag. Unfortunately, there is no way I could find to really test whether the code is working, as it requires examining the SQL generated for various operations. However, I have manually verified the fix. Please look at the output of the _JoinedSubclassAndSecondaryTable_ test, which has been modified as well, to verify the DML statements. Fix available for 3.6.5 upon request. github pull will be for 4.0 (master).
