Applying It All: The Mega App - JSF and HTML5 - page 351

The registration form includes the corresponding input fields to the Mega App user attributes, which were
described in Listing 13-9. When the user clicks the "Register User" command button, and using the <f:ajax>
tag, the registration form attributes are sent to the server, #{userAddBacking.registerUser} action method is
executed, and finally either a success message or a failure message(s) is rendered to the client. Listing 13-25 shows
UserAddBacking CDI managed bean.
