["Marc Logemann (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OPENJPA-1541?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13494857#comment-13494857 ] 

Marc Logemann commented on OPENJPA-1541:
----------------------------------------

I am still missing this feature heavily. Especially for Configuration Tables this would be really nice. Otherwise people continue to use static Strings as keys. old-school.

> Enums work as primary keys in TopLink and EclipseLink. DataNucleus supports them, too:
> http://www.datanucleus.org/products/accessplatform/jpa/primary_key.html
> It would be good to also include this in the specification because, not to support type safety in primary keys is fairly sad.
> Enum is a basic language feature, and most applications would enjoy significant benefits by mapping the keys of those little system behavior controlling lookup tables to enums.
> Consider a payment_type table. One can only generate the IDs of the table and use them for switching safely when the ids are mapped to enums. Any such application would typically have a PaymentType enum anyway.
