Olá, pessoal.
Estou a precisar de utilizar o Dialog Framework do Primefaces para ter uma lista e em seguida selecionar um artigo. Vi no Show case do Primefaces o exemplo e tentei fazer, mas não consigo ter resposta da seleção. Faz a lista mas não obtenho nenhuma resposta. Alguém me consegue ajudar? Aqui tem o meu código:
Esta é o meu faces-config:
<?xml version='1.0' encoding='UTF-8'?>
<faces-config version="2.2"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd">
<application>
<action-listener>
org.primefaces.application.DialogActionListener
</action-listener>
<navigation-handler>
org.primefaces.application.DialogNavigationHandler
</navigation-handler>
<view-handler>
org.primefaces.application.DialogViewHandler
</view-handler>
</application>
</faces-config>

@Named("dfCarsView")
@ViewScoped
public class DFCarsView implements Serializable {

	private static final long serialVersionUID = 1L;

	private List<Car> cars;
 
    @Inject
    private CarService service;
     
    public void init() {
        cars = service.createCars(9);
    }
     
    public List<Car> getCars() {
        return cars;
    }
 
    public void setService(CarService service) {
        this.service = service;
    }
     
    public void selectCarFromDialog(Car car) {
        PrimeFaces.current().dialog().closeDynamic(car);
    }

}
