I'm new with spring and I have a little problem with spring web flow. I have defined transitions on button click but when i click on button this mesage is shown in mesages tag

Unable to find matching navigation case with from-view-id '/login.xhtml' for action 'doLogin' with outcome 'doLogin'

and this is in log

WARNING: JSF1064: Unable to find or serve resource, /doLogin.xhtml.

and nothing happened.

        //UserDAOImpl u = new UserDAOImpl();
        //u.findByLogin(loginName);
        return true;
    }   
}

Can someone give me an advice what I'm doing wrong. Thank you very much for any advice.
