[SOLVED] Pass the parameter in Vaadin 14 between two routes

Pass the parameter in Vaadin 14 between two routes

Help me, please, to make navigating between views in vaadin application. In OrdersView class I create a link like

UI.getCurrent().navigate(FullOrderView.class, new RouteParameters("orderId", "123"));

In FullOrderView class I specify a route like this

@Route("order/:orderId")
public class FullOrderView extends AppLayout implements HasUrlParameter<String>{
    @Override
    public void setParameter(BeforeEvent event, String parameter) {
    }

but I get an error

java.lang.IllegalArgumentException: Navigation target 'com.example.crudwithvaadin.FullOrderView' requires a parameter.

If I remove a "implements HasUrlParameter" and setParameter() I get an error

No route found for the given navigation target 'com.example.crudwithvaadin.FullOrderView' and parameters '{}'

How do I fix the error and pass the parameter correctly? Thanks!

Solution

You are combining different Router features. The usage of Route template parameter (:orderId) has to be used in conjunction with BeforeEnterObserver instead of HasUrlParamter.
