[jboss-user] [JBoss Seam] - Re: unique=true attribute of primary key in generated class

[modoc]

AFAIK, it is an oracle specific constraint to not allow both a unique and primary key constraint on the same column.  It certainly works fine with postgresql and DB2.  

As for where the bug actually lies, that's a good question.  Probably need to file a bug against hbm2ddl to drop the unique constraint on Id columns for Oracle.  But there are other places to fix it, obviously.  

I'm surprised you're the first one to find this.
