Issue Type: Bug
Affects Versions: 3.4.0.CR1, 3.3.1.GA
Environment: OS: Windows XP
DB: HSQL
Reporter: yuanqingfei
@Before
public void setup() {

// enter all required fields
order.setName("order1");
order = orderDAO.save(order); //Hibernate should generate a timestamp here
}
@Test
public void testSave() {

System.out.println(order.getCreateTime()); //here should get a date.
}
Annotation part in Order:
@Temporal(TemporalType.TIMESTAMP)
@Column(insertable = false,updatable=false)
@org.hibernate.annotations.Generated(org.hibernate.annotations.GenerationTime.INSERT)
private Date createTime;
Save part in OrderDAO.
@SuppressWarnings("unchecked")
public T save(T object) {
return (T) super.getHibernateTemplate().merge(object);
}
every time, I just only get null.

Jim Cushing commented on ANN-749:
---------------------------------
You're misunderstanding what @Generated means. This indicates the value is generated
by the database. When you include this annotation, Hibernate will select the value from
the database after an insert and/or update (depending on your GenerationTime), such that
the in-memory entity has the proper value.
For example, used use @Generated if your database supports an auto-increment/identity
column for primary keys, or if you've got a value that's updated via a trigger.
