Data for our flow needs to be held in one or more flow-scoped named beans as
shown in the following code:
package com.ensode.flowscope.namedbeans;
import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.faces.flow.FlowScoped;
import javax.inject.Named;
@Named
@FlowScoped("registration")
public class RegistrationBean {
private String salutation;
private String firstName;
private String lastName;
private Integer age;
private String email;
private String line1;
private String line2;
private String city;
private String state;
private String zip;
@PostConstruct
public void init() {
System.out.println(this.getClass().getCanonicalName() + "
initialized.");
}
@PreDestroy
public void destroy() {
System.out.println(this.getClass().getCanonicalName() + "
destroyed.");
}
//getters and setters omitted for brevity
}
