This is a very simple registration form with Ajax-based validation. In other words, when we blur the
field (tab out or click outside), an Ajax request is fired. We start going through JSF phases. If there is a
validation error, after Process Validations, we go to Render Response. If there is no validation error, then
we finish all the phases, going through Update Model and Invoke Application. To see this in action, let’s
create a phase listener that will print a message to the console as we pass each phase.
In case you need to review the JSF phases, they are shown in Figure 2-4.
