Route not found issue

[thigg]

I'm getting RouteNotFound Errors after upgrading from 1.1.x to 1.2.8.

We're setting up with 2 packages:

routes = new Routes().autoDiscoverViews("company.view.view").autoDiscoverViews("company.testroutes");

initializing our own Servlet because we need weld:

MockVaadin.setup(MockedUI::new, new WeldMockVaadinServlet(routes, weld));`

Servlet and Service look like this:

public class WeldMockVaadinServlet extends MockVaadinServlet {

    private WeldInitiator _weld;

    public WeldMockVaadinServlet(final Routes routes, final WeldInitiator weld) {
        super(routes);
        _weld = weld;
    }

    @SneakyThrows
    @NotNull
    @Override
    protected VaadinServletService createServletService(@NotNull final DeploymentConfiguration deploymentConfiguration) {
        CdiMockService cdiMockService = new CdiMockService(_weld, this, deploymentConfiguration);
        cdiMockService.init();
        return cdiMockService;
    }
}

public class CdiMockService extends MockService {

    private final WeldInitiator _weld;

    public CdiMockService(final WeldInitiator weld, @NotNull final VaadinServlet servlet,
                          @NotNull final DeploymentConfiguration deploymentConfiguration) {
        super(servlet, deploymentConfiguration, MockedUI::new);
        System.setProperty("vaadin.i18n.provider",
                "company.infrastructure.translation.TranslationProvider");
        _weld = weld;
        addSessionInitListener(new SessionListener());
    }


    @Override
    protected Instantiator createInstantiator() throws ServiceException {
        BeanManager beanManager = _weld.getBeanManager();
        return new KaribuVaadinCDIInstantatior(this, beanManager);
    }
}

When doing UI.getCurrent().navigate(DefaultView.class, param); (DefaultView is in routes, I checked in the debugger):

com.vaadin.flow.router.NotFoundException: No route found for given navigation target!

	at com.vaadin.flow.router.RouteConfiguration.getUrlForTarget(RouteConfiguration.java:522)
	at com.vaadin.flow.router.RouteConfiguration.getUrl(RouteConfiguration.java:476)

Thank you for letting me know! In your WeldMockVaadinServlet.createServletService() you need to also call routes.register(service.context as VaadinServletContext), right before the return statement. Please take a look at the MockVaadinServlet class.

[thigg]

yes, that works. Thanks for the quick help!

What do you think how to progress from here. Add this as a note for migration from 1.1 to 1.2?
Provide another way to add CDI?

I'd propose to add this to the FAQ for now; if there are more users bitten by this then we can create a migration guide.
