Please, help me learn !!!
I have the following situation:
a Customer class with a collection of enums which represent weekdays { Sun,
Mon , Tue , ... }
( in JSF, I bind these to a UISelectMany component - checkboxes )
@Entity
public class Customer extends BaseLocation implements Serializable {
...
private List<DaysOfWeek> distDays = new ArrayList<DaysOfWeek>();
@CollectionOfElements( targetElement = DaysOfWeek.class )
@JoinTable( name = "Customer_DistDay" )
@Enumerated( EnumType.STRING )
@Column(name = "distDay", nullable = false)
public List<DaysOfWeek> getDistDays() { return distDays; }
public void setDistDays(List<DaysOfWeek> distDays) { this.distDays =
distDays; }
...
}
I also have a CustomerForm action which is modeled exactly like appfuse's
UserForm:
* edit() to initialize the backBean to an existing customer if (id != null)
or to a new customer;
* save(), which calls customer = customerDao.saveCustomer(customer) -
saveOrUpdate() with a flush();
* remove() calls remove from GenericDaoHibernate.
I have been battling a long time to get the LazyLoading working:
* First, I enabled
org.springframework.orm.hibernate3.support.OpenSessionInViewFilter for
everything in my path:
This got me the viewing power both in CustomerList and CustomerForm.
Nayice!
I can "add" a new Customer.
I can't "update" (NonUniqueObjectException: a different object with the
same identifier value was already associated with the session ... )
I can't "delete"
(org.springframework.dao.InvalidDataAccessApiUsageException: Write
operations are not allowed in read-only mode (FlushMode.NEVER/MANUAL) ... )
* Second, without much thinking/understanding, I extended my
org.springframework.orm.hibernate3.support.OpenSessionInViewFilter with the
recommended flush strategy from
http://wiki.apache.org/myfaces/Hibernate_And_MyFaces
http://wiki.apache.org/myfaces/Hibernate_And_MyFaces (it uses
FlushMode.COMMIT):
Now I got the views, "create" and "remove" working. SWELL
BUT "update" does not work (NonUniqueObjectException: a different object
with the same identifier value was already associated with the session ...
).
I suppose it's because the session, which contained it, no longer exists.
So, hibernate thinks I'm being stupid, maybe I am.
Please, help !!
