Hi, If Seam managed EntityManagers are being used, the Persistence Context propagates between the EntityManagers that are in the same conversation. This is very good and useful. I am just wondering if another component, for example an EJB is using an EntityManager in the same transaction as a Seam Component which has a Seam managed EntityManager, would the Persistence Context propagate. I doubt it. but just want to make sure that it is correct to say: "Seam only propagates persistence contexts between Seam managed EntityManagers used in the same web request?"
