There is a very good example in the sampler: http://demo.vaadin.com/sampler/#foundation/navigator
I don’t think i can explain it more easily…
Also take a look at https://vaadin.com/book/vaadin7/-/page/advanced.navigator.html if you didn’t already.

thanks very very much … very helpfull … also i found these …

" I’ve just wondered how can I use multiple View classes? I mean, without nested classes . "
