[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-4493) Support FK formula using named reference and avoiding the @JoinColumnOrFormula container

[Emmanuel Bernard (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-4493?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=34227#action_34227 ] 

Emmanuel Bernard commented on HHH-4493:
---------------------------------------

Well @MapKeyJoinColumn is really pointing to a different foreign key. ie unlike @Formula we are not composing columns (ie formula and join columns) to create one FK.
What was your reading of this annotation?
