[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=34240#action_34240 ] 

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

Well i this case, you can't gracefully degrade. By "ignoring" one formula, the non Hibernate provider will blow up claiming you have a FK / PK mismatch (for example 3 columns on the PK and only 2 properly declared on the FK - as the formula declaration is "missing")

That being said, we need to see if the code change to AnnotationBinder and co is disruptive or not. If not, we can add the feature as I said in the previous case, esp since the declaration is more elegant.

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