Hi,
On my framework 8 CDI project I obtained the instance of a view/context using the com.vaadin.cdi.CDIViewProvider by injecting the view provider to my UI like this.
@Inject
private CDIViewProvider viewProvider;
After that you got the view instance by using viewProvider.getView("name-of-view").
I’m trying to accomplish the same thing on Platform 14. For this, the class for which I want to get the instance of is like this.
@Route(value = "country-view", layout = MainView.class)
@PageTitle("Countries")
@RouteScoped
public class CountryView extends AbstractFormLayoutView<Country> {
//...
}
The documentation for Platform 14 suggests to use the BeanProvider (in Deltaspike). When I try to get it, I get a valid Bean, but the context is null. I’m doing this on my main layout after construction.
@Route("")
@Theme(value = Lumo.class)
public class MainLayout extends AppLayout {
@Inject
private GreetService greetService;
@Inject
private MongoDBDataConnection mongoDBConn;
@PostConstruct
public void init() {
// CODE TO OBTAIN INSTANCE GOES HERE
//ALTERNATIVE 1
//This returns a valid Bean with the correct class
Bean<?> bean = CDI.current().getBeanManager().getBeans(CountryView.class).stream().findFirst().get();
//Now to get the instance of the view
Context cntx = CDI.current().getBeanManager().getContext(RouteScoped.class);
Object instance = cntx.get(bean); //This returns null
//ALTERNATIVE 2
Object obj = BeanProvider.getContextualReference("country-view", true); // THIS RETURNS NULL
}
Any ideas or alternatives that work are welcome!
Thanks.
