      Hi,

       

      I've a simple test which loads some info during pre-render view phases and then send this info when submiting. The object where this info is loaded is produced at the backing bean

       

      @Produces 
@Named 
private Email newEmail = new Email();

       

      and the info is loaded at the two pre-render view phase listeners

       

      newEmail.addDestinatary(destinatary);
...
newEmail.setSubject(emailTemplate.getSubject());
newEmail.setText(emailTemplate.getText());

       

      When the submit button is clicked the newEmail object still holds the subject and the text values but the list is empty

       

      The Email class is a very simple entity holding a list and two String fields

       

      @Entity
public class Email implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue
    private long pk;

    @OneToMany
    private List<Customer> destinataries;
    private String subject;
    private String text;

    public Email() {
        this(null, null);
    }
    
    public Email(final String subject, final String text) {
        this.destinataries = new ArrayList<Customer>();
        this.subject = subject;
        this.text = text;
    }

    public long getPk() {
        return pk;
    }

    public void setPk(long pk) {
        this.pk = pk;
    }

    public List<Customer> getDestinataries() {
        return destinataries;
    }

    public void setDestinataries(List<Customer> Destinataries) {
        this.destinataries = Destinataries;
    }
    
    public void addDestinatary(final Customer destinatary) {
        destinataries.add(destinatary);
    }

    public String getSubject() {
        return subject;
    }

    public void setSubject(String subject) {
        this.subject = subject;
    }

    public String getText() {
        return text;
    }

    public void setText(String text) {
        this.text = text;
    }

    @Override
    public String toString() {
        StringBuilder builder = new StringBuilder();
        builder.append("Email [to=").append(destinataries).append(", subject=")
                .append(subject).append("]");
        return builder.toString();
    }

}

       

      Why could this be happening?
