Hi,

I'm having trouble getting my PrePersist or PreUpdate annotation to fire.

My config
~~~~~~~~~~~~~~~~~~~~~~~
JDK=1.6.0_13
Hibernate-dist=3.3.1
Hibernate-annotations=3.4
Hibernate-entitymanager=3.4
~~~~~~~~~~~~~~~~~~~~~~~~~

my Hibernate.cfg.xml (no orm.xml specified/used):
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
<hibernate-configuration>
<session-factory>
<property name="hibernate.bytecode.use_reflection_optimizer">false</property>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.password">codefu</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost/invest</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.current_session_context_class">thread</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<mapping class="com.invesys.invest.dao.User" />
<mapping class="com.invesys.invest.dao.EventImpacts" />
</session-factory>
</hibernate-configuration>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

User POJO class with annotations(generated by hibernate tools, then hand editted):
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
package com.invesys.invest.dao;

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

When I create a new User record I don't see my PrePersist get called.
And when I update an existing User record, I don't see my PreUpdate get called.
I don't use the orm.xml (it doesn't appear to be needed?)

For creating a new user I do:
~~~~~~~~~~~~~~~~~~~~~
user = new User() ;
user.setName(name);
user.setEmail(email);
user.setPasswordHash(password);
session.save(user);
session.getTransaction().commit();

But the user.createdAt field is null, and it get's stored in the database as "NULL".

Any ideas?

Thanks much in advance.
