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

[Paul Benedict (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-4493?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=34221#action_34221 ] 

Paul Benedict commented on HHH-4493:
------------------------------------

JPA 2.0 introduced @MapKeyJoinColumn and @MapKeyJoinColumns, which I think is very similar to what is trying to be done here. There is @JoinColumn(s) for basic columns, @MapKeyJoinColumn(s) when columns key a map, and I propose re-factoring to allow a @FormulaJoinColumn(s) for formulas.

> First question, is it desirable? Does the benefit outweight the additional documentation complexity (of two different approaches).
