How to annotate a single class as two different managed beans?

Question

I've created an address bean and I want to use it twice - once for street address and once for mailing address. I can achieve this using faces config as per the below, but I'm wondering if I can do this via annotations.

e.g. put @ManagedBean(name="StreetAddress") and @ManagedBean(name="MailingAddress") on the same class? I feel like I am missing something obvious here but I'm not sure what.

<managed-bean> <managed-bean-name>MailingAddress</managed-bean-name> <managed-bean-class>com.leetb.jsf_ex1.model.AddressBean</managed-bean-class> <managed-bean-scope>session</managed-bean-scope> <map-entries/> </managed-bean> <managed-bean> <managed-bean-name>StreetAddress</managed-bean-name> <managed-bean-class>com.leetb.jsf_ex1.model.AddressBean</managed-bean-class> <managed-bean-scope>session</managed-bean-scope> <map-entries/> </managed-bean> public class AddressBean { private String line_one; private String line_two; private String suburb; private String state; private String postcode; /* getters and setters snipped */ }

You've there a design mistake. Those look more like model classes than backing bean classes. Model classes shouldn't be managed beans at all. Make them a property of a backing bean class and manage it instead.

E.g.

@ManagedBean @ViewScoped public class AddressBacking { private AddressBean mailingAddress; private AddressBean streetAddress; @PostConstruct public void init() { // Prepare them here yourself. For example, when it's for a new entry. mailingAddress = new AddressBean(); streetAddress = new AddressBean(); } public void save() { // ... } // ... }

(I'd rename AddressBean to Address by the way)

and use it as follows

<h:inputText value="#{addressBacking.mailingAddress.line_one}" /> ... <h:inputText value="#{addressBacking.streetAddress.line_one}" /> ...

Thanks - Ive been mixing up my class model and object model. Need to start thinking differently.
