Pass and receive data in Vaadin 8

I have a view:

@SpringUI(path="order")
@Title("order")
public class OrderGUI extends UI{

and I would pass parameter to other:

@SpringUI(path="orderNumber")
@Title("Order number")
public class GetOrderNumber extends UI {

I tried to send parameter(orderNumber) by:

getUI().getPage().setUriFragment(orderNumber);
getUI().getPage().setLocation("orderNumber");

then it goes to /orderNumber but when tried to catch it by:

String fragment = getPage().getUriFragment();

but 

System.out.println("Fragment: " + fragment);

says that Fragment: null

How to send parameter from one Vaadin view to another?

@Edit It is close to work. I have changed my View to:

@SpringView(name = "GetOrderNumber")
@Title("Order number")
public class GetOrderNumber extends VerticalLayout implements View {

and in @SpringUI made getUI().getNavigator().navigateTo("GetOrderNumber/" + orderNumber); it actually still throws java.lang.IllegalArgumentException: Trying to navigate to an unknown state '' and an error view provider not present but it works. I mean all the time when I go to localhost:8080/order the 

@SpringUI(path="order")
public class OrderGUI extends UI {

throws an error but then works as expected - go to view and pass parameter right. I have no idea why navigator = new Navigator(this, this); cause an error

@SpringUI annotation defines always just the name of the view, it is not the place where you give the URI parameter, the correct place is the navigateTo(..) method, e.g.:

getUI().getNavigator().navigateTo("myview/someparameter");
