1. On each commandLink or commandButton, you have two things you can specify: action and actionListener. The actionListener gets called after the link is clicked and all your data successfully updates to your managed beans. It executes the business logic you need. The action you specify is passed to your the navigation handler to tell it what page to direct the user to.
In general, you shouldn't need multiple forms on a page for cases like this. You just need different actions for your commandLinks. 2. What we are doing in our app is using stateless navigation cases. What this means is that you can go anywhere from anywhere. As far as I see it, the <from-view-id> is just a way of defining a namespace for the navigation cases. So, just get rid of the <from-view-id>s and you should be good to go.
