Getting username from url only works after refresh

My login based application, requires to always know the username of the logged in user. (MVP) . So I'm getting the username from the url, but when the page opens after the login succeeded, I can't get the username from the url, because it does not appear to exists, but it is there. It only works after a refresh. Then I'm able to get the username.

The URL is in the form, where I'm splitting the String to only get the admin part.

I thought this is because it downloads the code before verifying the user. So I placed a split point in my code like this: (I don't know if I placed it correctly)

loginButton.addClickHandler(new ClickHandler() {            @Override          public void onClick(ClickEvent event) {              final String username = usernameBox.getText();              final String password = passwordBox.getText();              GWT.runAsync(new RunAsyncCallback() {                    @Override                  public void onSuccess() {                      performUserConnection(username, password);                  }                    @Override                  public void onFailure(Throwable reason) {                      // TODO Auto-generated method stub                  }              });          }      });      private static void performUserConnection(String username, String password) {      DBConnectionAsync rpcService = (DBConnectionAsync) GWT.create(DBConnection.class);      ServiceDefTarget target = (ServiceDefTarget) rpcService;      String moduleRelativeURL = GWT.getModuleBaseURL() + "DBConnectionImpl";      target.setServiceEntryPoint(moduleRelativeURL);        rpcService.authenticateUser(username, password, new AsyncCallback<User>() {            @Override          public void onSuccess(User user) {                if (user.getType().equals("User")) {                  String username = user.getUsername();                  presenter.goTo(new UserPlace(username));              } else if (user.getType().equals("Admin")) {                  String username = user.getUsername();                  presenter.goTo(new AdminPlace(username));              }          }        }  }

This is happening when the user clicks the login button. Is the split point placed correclty, or not ? How can I get the username without needing to refresh the page after a successful login ?

Thanks in advance
