You update not with the persist method but with the merge method:
So you can do
| @Name("customerAction")
| @Scope(<PUT SCOPE HERE>)
| @Stateful
| public class CustomerAction {
|
|
| @PersistenceContext(....);
| private EntityManager em;
|
| @DataModel
| private List<Customers> customers;
|
| @DataModelSelection
| private Customers customer;
|
| @Factory("customers")
| public void find()
| {
|
| customers = em.createQuery("select c"+
| "from
Customers c " +
| "where
c.userId = :userId")
|
.setParameter("userId", user.getUserId())
|
.getResultList();
|
| }
|
| public void update() {
|
| em.merge(customer)
| }
| }
|
|
