org.hibernate.LazyInitializationException: Seam or Hibernate
Not sure where to post this so it's on the hibernate forum as well. I'm new to ejb, seam and hibernate so please excuse my ignorance.
I have a simple query that retrieves an entity from the database. Within that object I call a method to get a collection of different entitys.
Like so...
List<Object> l = entity.getCollection();
From searching google and reading posts I understand that I have a session issue and could fix the problem by using and EAGER strategy. However, I cannot get the eager to work either. I get the same error regardless of what I do.
I'm running the lastest version of JBoss AS and Seam.
Here's the actual code.
@DataModel
private Set<RemittanceItemEntity> remitItems;
remitItems = packages.getSelectedClosedPackage().getRemittanceItems();
-----------------
Here is the entity bean method with annotations
@OneToMany(mappedBy="remittancePackage")
public Set<RemittanceItemEntity> getRemittanceItems() {
return remittanceItems;
}
Here's the exception...although I'm sure you guys have seent this one before...
