Navigator

I have this: a view said A for insert some parameters for search on DB; the result is displayed on view B (a table) with Navigator.navigateTo(“viewB”). I go back on view A for changing the parameters and I ri-Navigator.navigateTo(“viewB”). I didn’t find the method for refreshing the table on view B.
A request: it’s possible to have the reference to the views registered to Navigator? And a back button?
Thanks in advance

All it’s ok. I’ve found one bug in my prog.
