Trying to understand @Out
I have this code
@Out(required=true)
private List catalogs;
@Factory
@SuppressWarnings("unchecked")
public void getCatalogs() {
catalogs = em.createQuery("select catalog from Catalog catalog").getResultList();
}
The documentation I read says that if I have a factory method operating on my field catalogs, it should be annotated with
@Out(required=false)
My code still works, so I can't understand the difference.
Annotation help for required on @Out says
"Specifies that the outjected value must not be null, by default."
Not getting it here, does that mean if the value is null, a new object of that type will be created ?
Also not real sure of use of Factory methods. Let's say when User A first hits the page, the factory method would populate the list. User B is also making changes on this page, how will user A see these changes if factory method is called only once. Should I program instead an init method using page.xml ?
Thanks in advance
