[jboss-user] [JBoss Seam] - simulate a multi-page transaction or not ?

In Yuan & Heute's book version 12/6/2006 in section 9.4 "Simulate a Multi-page Transaction" ... method confirm() is annotated @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED) and contains a call em.flush(). Per javax.persistence.EntityManager though for method flush() it @throws TransactionRequiredException if there is no transaction. You see that, TransactionAttributeType.NOT_SUPPORTED would trigger that @throws TransactionRequiredException if there is no transaction, right? Is section 9.4 speculation (as of 12/6/2006) or is anyone really using it? Any insights? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4001131#...
