Hi, Usng the new-entity switch for seam.bat generates an entity with the above annotation on the id field. However I don't seem to be able to get the same behavior with generate-entities. Is there something I should do in the database schema for this to happen? Currenly using mysql 5 and the id field is set as auto incrementing. Otherwise this tool is really sweet! Thanks, Andy.
