Steve Ebersole commented on HHH-7225:
-------------------------------------
I assume you mean a nullable entity association (FK) that is part of a natural-id?
> NullPointerException after persisting null entity value as natural-Id
> ---------------------------------------------------------------------
>
> Key: HHH-7225
> URL: https://hibernate.onjira.com/browse/HHH-7225
> Project: Hibernate ORM
> Issue Type: Bug
> Components: core
> Affects Versions: 4.1.2
> Reporter: Guenther Demetz
> Priority: Minor
> Labels: naturalid
> Attachments: TestCaseHHH-7225.jar
>
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> This request is basically a reopening of HHH-7158.
> story-line:
> -Fixing of HHH-7158 did successfully solve both attached testmethods, but only the first one was integrated into hibernate matrix tests.
> -Fixing of HHH-7206 did slightly change the way how natural-id-vales are compared, causing now testmethod2 fail again.
> before HHH-7206:
> {code}
> // lengths have already been verified at this point
> for ( int i = 0; i < naturalIdTypes.length; i++ ) {
> if ( ! naturalIdTypes[i].isEqual( naturalIdValues[i], values[i] ) ) {
> return false;
> }
> }
> {code}
> after HHH-7206: (please notice now there has appeared *persister.getFactory()* as third parameter)
> {code}
> // lengths have already been verified at this point
> for ( int i = 0; i < naturalIdTypes.length; i++ ) {
> if ( ! naturalIdTypes[i].isEqual( values[i], otherValues[i], persister.getFactory() ) ) {
> return false;
> }
> }
> return true;
> {code}
> Proposed solutions:
> Either revert back to using the isEqual method again with 2 parameters only,
> or alternatevely make method
> EntityType#isEqual(Object x, Object y, SessionFactoryImplementor factory)
> stable against null x,y values as proposed in HHH-7158.
> I don't know which one is the better solution, but both solution make the attached testcases go through without fails.
