[nhibernate-issues] [JIRA] Commented: (NH-1452) Join element doesn't support keys with property-refs

[NHibernate J. <nh...@gm...>]

    [ http://jira.nhibernate.org/browse/NH-1452?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17467#action_17467 ] 

Jozef Sevcik commented on NH-1452:
----------------------------------

Patch I attached will not work for persistence/HQL.
It can fix loading entities that uses <join> with <property-ref> but when saving, primary key of parent is still used. Haven't tested HQL, but I assume it will not work properly.
There are two options:
1. Add support for persistence/HQL/StatelessSession also (http://opensource.atlassian.com/projects/hibernate/browse/HHH-1829?focusedCommentId=26029#action_26029 may be helpful, but it's not trivial IMHO)
2. Completely revert this feature (which has never been supported by Hibernate, e.g. <join> with <property-ref> has never been implemented in Hibernate, see Gavin response here: http://forum.hibernate.org/viewtopic.php?t=937111)
Problem is that 'property-ref' remains in XSD schema for <join><key>, that's why people tend to think this should work and it's bug if it does not work.

> The <join> element does not use the property-ref attribute on it's <key>.
