[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-1829) Allow join on any property using property-ref

[Robert Field (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1829?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=33996#action_33996 ] 

Robert Field commented on HHH-1829:
-----------------------------------

A project I am associated with has been successfully using HHH-1829-mwinkels.patch with 3.2.5 for a year now.  It was applied by hand, because the patch command didn't work cleanly with that hibernate version.

There are only a couple of minor problems with it that I can see.

1) It seems to always use outer join when joining on a non-primary key, which doesn't really matter for the query we are doing.

2) Another project team that was using our patched jar,  found an API difference between the patch and unpatched hibernate.

> Currently joining tables for one class (uing the <join...> tag) is only supported for the id property. The property-ref is allowed on the <key..> tag inside the <join..> tag, but this is ignored.
