[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-6347) @Formula with Enum caussing NPE

[Ondrej Medek (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-6347?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=42690#action_42690 ] 

Ondrej Medek commented on HHH-6347:
-----------------------------------

Or maybe what about to fix org.hibernate.mapping.Column.getName() to return the formula when the Column is created from Formula? I see the method Column.getName() is used at more places in the Hibernate code where is may be useful.
