i am a user of tomee 1.7.2 plus .and 1.7.4 plus and 7.0.2 plus .
I have tried to generate a crud web app.
Into my domain model i have for example a entity Customer with @OneToMany
Collection<Order> collectionOrders.
And a Entity Order with @ManyToOne Customer customer.
I would use the default lazy fetch type for orderscollection into Customer
entity.
>From a view jsf page i show the list of customer inside a table
When i click on the row , with ajax i set the selected customer into the
viewScoped customerController .
So into the customerController i call a EJBFacede and i reattach the
custoemer to em and retrive
the orderslist.. with :
inside the EJB:
public Customer reattachandLoadORdersCOllection(Customer customToReattach){
Customer attached=em.merge(customToReattach).
Collcetion<Orders> collection= atrtached.getOrdersCollection();
collection.size();
customToReattach.setOrdersCOllection(collection):
return customToReattach
}
i set the collection to to customer and i return it to controller.
Into the controller i take the Customer returned from the ejb with
ordersColletion and i set to field Customer selected.
so i you ask please :
On tomee or some github repo it is present a working solution from a Tomee
plus that uses OpenJPA and CDI and has AJAX elements where they need to
access LAZY relationships.?
OR that show how resolve the lazy loading
I would understand like resolve the lazi loading with tomee openjpa
tank you in advance.
