Thanks for the clarification Gavin. I guess now the forum is the only place for me.
I notice that this issue (http://jira.jboss.org/jira/browse/JBSEAM-843) is still not on the roadmap. (I recall that this had just missed the 1.1.7 release, but I had hoped that it would have been included in the 1.2.x release, and now I don't even see it scheduled for 1.3.)
Please don't forget about it because I am trying to promote a Java-first approach whereby the Entity beans begin as Java code, not a database table, and the DDL is derived from the Java code. (This helps ensure that the Java annotations are correct and complete.)
I'm not really sure of the status, you'll have to see what max says.
