Thanks for your quick reply! A few more questions: anonymous wrote : Hibernate always does an immediate INSERT when you use generated ids. This is something we need to fix in Hibernate. | Steve says I'm wrong and that this now works in Hibernate. 1) Does this mean, that with the new Hibernate version only SMPC with FlushModeType.MANUAL is required, and no additional annotations like @TransactionAttribute are necessary? 2) In which Hibernate version is this fixed? 3) With Seam there comes "hibernate-all.jar". How can this be updated to solve the problem? Thanks again! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4020754#...
