URI Clean up

Vaadin 6 / 7 / 8
1

Good day,
I’m having an issue where I’m unable to get rid of URI parameters included in a link sent to users. Here is the situation;
I send a link to users in the form
http://mysite/myapp?token=91792a8de1e011e5b8f5303a64b3cc11
This link redirects them to a secure page as follows

    protected void init(VaadinRequest request) {
        navigator = new Navigator(this, this);
        String token  = request.getParameter("token");
        if (Util.isNotEmpty(token)) {
            getUI().getCurrent().getSession().setAttribute(TOKEN, token);
            navigator.navigateTo("createPassword");
        }else{
            navigator.navigateTo("login");
        }
    }

Once the user is done creating the password, they are redirected to the login page by the code snippet

navigator.navigateTo("login");

and the resulting URI is

http://mysite/myapp/?token=91792a8de1e011e5b8f5303a64b3cc11#!login

And the parameter hangs around continuously (when I log into the application and navigate around)
How do I rewrite the URI to

http://mysite/myapp/#!login

Navigator uses uri fragment, which doesn’t send page load so the url doesn’t change. Use Page.getCurrent().setLocation(uri) until you have logged in the user and then use navigator after that.

@Johannes, Thanks but I already tried that and it resulted in

I'm using the CDIViewProvider (added to the navigator) to manage my views, have no way of doing so with the Page.
