Hi, I've got a big problem with my EJB transactions.
I've a first Entity EJB : EiUser
I've a second Entity EJB : EiAccount
The EiAccount
class has a EiUser
attribute.
Both EJBs are correctly mapped to the database.
I have also two JSF pages, the first one is to create an EiUser
, and the second one to create an EiAccount
.
To do that, I created two Stateful Session EJBs :
Here is UserBean :
@Stateful
@Name("userBean")
@Scope(ScopeType.SESSION)
public class UserBean implements IUser {
@In
@Out(scope=ScopeType.SESSION,required=true)
EiUser eiUser;
@PersistenceContext
EntityManager em;
@Logger
private static Log log;
@Begin(join=true)
public void begin()
{
log.info("begin");
}
public String add()
{
log.info("add user");
try
{
em.persist(eiUser);
}catch (Exception e) {
log.info(e);
}
return "/newaccount.xhtml";
}
@Destroy @Remove
public void destroy()
{
log.info("destroy UserBean");
}
}
And here AccountBean :
@Stateful
@Name("accountBean")
@Scope(ScopeType.SESSION)
public class AccountBean implements IAccount {
@In(required=false)
@Out(required=false)
private EiAccount eiAccount;
@In(scope=ScopeType.SESSION, required=true)
private EiUser eiUser;
@PersistenceContext
private EntityManager em;
@Logger
private static Log log;
public String createTempAccount()
{
log.info("createTempAccount");
try
{
eiCompte.setUser(eiUser);
em.persist(eiAccount);
}catch(Exception e)
{
log.info(e);
}
return null;
}
@Destroy @Remove
public void destroy()
{
log.info("destroy compteBean");
}
}
On the first JSF page, I call the function Add(), then the User is correctly added to the database, and on the second JSF page, I call the function createTempAccount() but I got this message :

In this message, I could understand there is a problem with eiUser : this entity is persisted, but on the second page, I can look that its Id attribute (EiUser.code) is not updated, whereas in the database, it's correctly added. I tried to manually flush by the EntityManager, but it doesn't do anything.
What could I do ?
Thanks !

Hi,
you should use @PersistenceContext(EXTENDED) to get this work.
http://www.seamframework.org/Community/HelpJavaxpersistencePersistenceExceptionOrghibernatePropertyValueExceptionNotnullPropertyReferencesANullOrTransientValue
Is there a way I can configure in seam that it should not call hibernate on a link click ...
I am getting exception as
--------------------------------------
Hibernate:

-------------------------------------
Try to flush the entity after persisting.
em.persist(eiUser); em.flush();
So either you should flush your changes after saving user or you should have an extended entity manager and flush it after saving account. Let us know if it worked.
