My EntityManager is injected to my session scoped and I have 3 methods:
@PersistenceContext(type = EXTENDED)
private EntityManager em;
public String list(){
...
}
public String edit(){
...
}
public String save(){
...
}
In list method, I retrieve a collection of data from db. in edit(), I start to edit for a single entity. in save(), when I try to use em.persist(myentity) or em.merge(myentity). I get java.lang.IllegalArgumentException: Entity not managed.
If I change my ejb to conversation scoped, the problem would disappear. Any idea?
