[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Re: Transactions and strange behaviour

[gusgorman]

Hello again, more info now.

I now understand that the session is being flushed when I commit a transaction, and  that is why updates are occuring to Question objects at that point. But why does hibernate think that these objects are dirty? They definately shouldn't be.

I have implemented Audit logging using the idea suggested here:

http://209.85.229.132/search?q=cache:Wg61eqMQfGcJ:www.hibernate.org/48.html+usertype+for+audit+info+logging+site:hibernate.org&cd=1&hl=en&ct=clnk&gl=uk

Each entity that needs audit logging has the following xml in its mapping file:

  <property name="AuditInfo" type="BCS.QMIS.DataAccess.Hibernate.CustomTypes.AuditInfoType, QMISDataAccess">
  |       <column name="WhenAdded" />
  |       <column name="WhenUpdated"  />
  |       <column name="AddedBy"  />
  |       <column name="UpdatedBy"  />
  |     </property>
  | 

If I remove this piece of xml from the Question.hbm.xml file then stage 3 of my first post does not happen, ie no unwanted updates occur and the version is not incremented. Any ideas?

Many thanks in advance,
Jordan.
