Getting "Injection point has ambiguous dependencies", but there is only one producer

Anders Åberg Newbie

Hi guys
I am experimenting with a @Producer method in order to allow injection of a POJO:



@SessionScoped
public class UserDataProducer implements Serializable {

    private UserData userData;

    @Produces
    public UserData getUserData() {
        if (userData == null) {
            userData = new UserData();
        }
        return userData;
    }

}



The UserData class is a plain Java object, not @Named, @ManagedBean or anything:



public class UserData implements Serializable {

    private String uid;
    private String culture;
...
}



However, when trying to inject this I get this exception:


Injection point has ambiguous dependencies. 
Injection point: field no.evote.presentation.MessageCatalogImporter.userData; 
Qualifiers: [@javax.enterprise.inject.Default()]; 
Possible dependencies: [
org.jboss.weld.bean-/C:/Dev/glassfish-3.0.0-eclipse/glassfish/domains/domain1/eclipseApps/admin-web/-ManagedBean-class no.evote.security.UserData, 
org.jboss.weld.bean-/C:/Dev/glassfish-3.0.0-eclipse/glassfish/domains/domain1/eclipseApps/admin-web/-ProducerMethod-no.evote.presentation.util.UserDataProducer.getUserData()
]



What I don't understand is why Weld reports UserData as a -ManagedBean-. As far as I can tell there is only one valid producer here, UserDataProducer.getUserData().


Am I missing something here? Is there any way I can mark UserData as unmanaged?


BTW, the reason UserData is a POJO and not a managed bean is that it causes some strange errors when passed as parameter to remote EJB's. Maybe not that strange really since there is no session on the server.
