Passing URL GET parameters to Vaadin 7 app

Vaadin 6 / 7 / 8

Hello

I have such class:


public class Main extends UI
	{   
		private String lang;
		private String id;
		
		@Override
		protected void init(VaadinRequest request) 
			{
				getSession().addRequestHandler(new RequestHandler()
					{
						@Override
						public boolean handleRequest(VaadinSession session,
								VaadinRequest request, VaadinResponse response)
								throws IOException {
							
							Map<String, String[]> map = request.getParameterMap();
							this.lang = request.getParameter("lang");
							this.id = request.getParameter("id");
							
							return false;
						}						
					}				
				);	
				
				getPage().addUriFragmentChangedListener(new UriFragmentChangedListener()
					{
						@Override
						public void uriFragmentChanged(UriFragmentChangedEvent source) 
							{
								enter(source.getUriFragment());
							}
					}
				);
				
				Navigator navigator = new Navigator(this, this);
				navigator.addView(MainAppView.NAME, new MainAppView());
				navigator.addView(FormAppView.NAME, new FormAppView());
			}	

		private void enter(String uriFragment) {			
			
		}
	}

When I am trying to access FormAppView and pass parameters to it like this: http://localhost:8080/MainApp/#!FormAppView/?lang=en&id666 using getParameter() I always got request.getParameter(“lang”); and request.getParameter(“ld”) = null. Does anyone know where is the problem? I missed ParameterHandler features from Vaadin 6… That’s was awsome when you could just parse query string to Map.

If you want to pass the parameters as URL parameters they need to come before the hash, so http://localhost:8080/MainApp/?lang=en&id666 #!FormAppView/
