Hi,
I am encountering a problem with Hibernate.
In a method I need to save a first object then I call a second method and try to save a second object. I encounter a problem (not an exception) when saving the object.
I am using
Hibernate version: 3.2.0CR2
Spring-hibernate Version : 2.0 CR1
Spring : 1.2.8
My Code :
Code:
@transactional
public void GeneralMethod() {
Method1();
}
public void Method1(){
generate Object1()
getMyDao().update(Object1);
method2();
}
public void method2() {
lBroadcast.setCsaCategory(lCsaCat);
lBroadcast.setDuration(lDuration);
getBroadcastEventDao().update(lBroadcast);
}
The getBroadcastEventDao() and getMyDao calls this Dao Method :
Code:
public class GenericDAOHibernateImpl<T> extends HibernateDaoSupport implements IGenericDAO<T>
{
private static Log sLog = LogFactory.getLog(GenericDAOHibernateImpl.class);
/**
* save a single object
*/
public void save(T pObject)
{
// Vérification.
if (pObject == null)
{
throw new IllegalArgumentException("pObject est null");
}
// Met à jour l'objet.
getSession(true).persist(pObject);
}
/**
* update a single object
*/
public void update(T pObject)
{
// Vérification.
if (pObject == null)
{
throw new IllegalArgumentException("pObject est null");
}
// Met à jour l'objet.
getSession(true).merge(pObject);
}
I try with My save or update methods but I have the same problem no saving of my objects.
If I don't call my method2, Object1 is persisted in my DB.
If somebody has an idea it may be helpful
thanks
thomas
