Oh, you mean in plain Hibernate, not in HEM. This is again correct.

RE: [Hibernate] Flush behavior
I don't understand what is so difficult to understand here. Persist() is no different to delete(), merge() or evict() in this respect. You have to explain things in terms of what operation is applied at flush time. In the case of Hibernate it is the save/update operation. In the case of EJB3 it is the persist operation. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Christian Bauer Sent: Monday, November 21, 2005 6:18 AM To: Hibernate development Subject: Re: [Hibernate] Flush behavior On Nov 21, 2005, at 2:46 PM, Christian Bauer wrote: Why?

RE: [Hibernate] Flush behavior
Negative. Hibernate cascades the saveOrUpdate() operation, EJB3 cascades the persist() operation. They should and are quite different. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Christian Bauer Sent: Sunday, November 20, 2005 3:43 AM To: Hibernate development Subject: [Hibernate] Flush behavior http://opensource.atlassian.com/projects/hibernate/browse/HHH-1181 They should be synchronized, if we have the same methods on Session and on EM, they should do the same. --- This SF.Net email is sponsored by the JBoss Inc.
