Interesting. I'm definitely still novice to java, especially use of
'static', even though i used it, primarily, for adding static strings
throughout the app. All along, I knew that 'static' means that only one
copy will be created/instantiated within/for the parent class.
I think the static reference was added (by Netbeans, when it generated the
code for me, back in 2011), because of the following:
Below, you will see that the managed bean has a reference to a stateless
@EJB (DAO),
@ManagedBean(name = "customerController")
@RequestScoped
public class CustomerController implements Serializable {
@EJB
private jpa.session.CustomerFacade ejbFacade;
and, the CustomerControllerConverter.getAsObject() method references the
@EJB which is a member of the managed bean, CustomerController. See below.
CustomerController controller = (CustomerController)
facesContext.getApplication().getELResolver().
getValue(facesContext.getELContext(), null,
"customerController");
return controller.ejbFacade.find(getKey(value));

Will try this and let you know. I think it still may be necessary to add
the class as a 'public static' class, so there will be only one instance of
@FacesConverter(forClass = Customer.class) during runtime.

Yeah, I really prefer not to use converter id, or I would have to go all
throughout my xhtml and update, accordingly. Thanks.
Will share any/all updates, ASAP. Thanks Mike!
