<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>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/#transactions-demarcation-exceptions>)
states that if any method throws an exception, the session must be closed.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>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.<o:p></o:p></span></font></p>
