Suppose a field has a validator, and the field is made invalid (age < 0). When flushing, the validator runs, and throws an exception. The exception handling section (<http://www.hibernate.org/hib_docs/v3/reference/en/html_single/#transactio... >) states that if any method throws an exception, the session must be closed. So, what to do if session-per-conversation is used? If hibernate validation is used, then flush of invalid data corrupts the session – the application then needs to ask the user to start over, or else build complex recovery logic (new session, copy data to new session) - effectively reducing session-per-conversation to session-per- transaction, since the application needs to be able to replay transactions that fail due to validation. How does hibernate validation interact with extended sessions? -Justin office 8-383-6725, 212-272-6725; cell 917-861-6042 *********************************************************************** Bear Stearns is not responsible for any recommendation, solicitation, offer or agreement or any information about any transaction, customer account or account activity contained in this communication. *********************************************************************** _______________________________________________ hibernate-dev mailing list hibernate-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev
