I'm looking any answer of my question and i've found that the "start_path = '/app/Settings/login' " is a solution but when a i change that and then use the login page it bring me back to the my login page.
What can I do to refer my login start up page to the next page( my menu page)??????
Well, you need to understand that Rhodes/RhoElements work in a Model-View-Controller (MVC) type of architecture: User clicks a link, a controller method is called (which might/might not access the model, depending on your needs), the method does some processing and then the related View is rendered.
Maybe you need to read the docs more ...
