My Jsf pages are all ready, then I need dynamically catch a phase before
render, look each component in this page an look in the database if this
field just be rendered.
I think i need put an phase listener... if is true... where I can read how
make this?
Yes, a phase listener is the strategy you'd want for this. The basic idea would be to have the backing bean for your page register itself (probably in the constructor) as a phase listener for the Render Response phase, and then in the beforePhase() event handler you'd do the scan of components and set the "rendered" properties appropriately. Don't forget to also deregister yourself as a listener (in the afterPhase() event method) to avoid memory leaks.
Or, just use Shale's ViewController API, and put your "check the database" code in the prerender() method. Shale will do all the event listener wiring for you, so you don't have to.
