Jsf Primefaces表单值不显示

我有一个primefaces数据表，我想编辑它的行。我确实提交了行的Id，并在要编辑的面板中显示了值。使用相同的对象，如果我使用h:outputText打印出值，我会看到这些值。p:inputText不显示该值。如果我使用浏览器的“重新加载”按钮刷新页面，表单值会显示得很好。下面是我的代码的浓缩版本

型号

@Entity
@Table(name = "TICKET")
public class Ticket extends AuditTrail implements Serializable 
{
    private static final long serialVersionUID = 1L;

    private static Logger log = Logger.getLogger(Ticket.class);

    @Id
    @SequenceGenerator(name = "TICKET_TICKETID_GENERATOR", sequenceName = "TICKET_SEQ")
    @GeneratedValue(strategy = GenerationType.AUTO, generator = "TICKET_TICKETID_GENERATOR")
    @Column(name = "TICKET_ID", unique = true, nullable = false, precision = 0)
    private Long ticketId;

    @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "ticket")
    @OrderBy(clause = "createdBy")
    private Set<Comment> comments = new LinkedHashSet<Comment>(0);
}

@Entity
@Table(name = "COMMENT_LOG")
public class Comment extends AuditTrail implements java.io.Serializable {

    // Fields

    private static final long serialVersionUID = 1L;

    @Id
    @Column(name = "COMMENT_LOG_ID", unique = true, nullable = false, precision = 0)
    @SequenceGenerator(name = "COMMENT_COMMENTID_GENERATOR", sequenceName = "COMMENT_SEQ")
    @GeneratedValue(strategy = GenerationType.AUTO, generator = "COMMENT_COMMENTID_GENERATOR")
    private Long commentId;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "TICKET_ID")
    private Ticket ticket;

    @Column(name = "COMMENT1", nullable = false, length = 300)
    private String comment1;

}

谢谢你的帮助

似乎是我无意中删除了commandLink中的豪门=“@this”

<p:commandLink  action="#ticketBean.editComment(com.commentId)}"                                                                                
            ajax="true" 
            value="Edit"                              
            process="@this" 
            update=":tabView:commentForm1" 
            immediate="true"/>

为什么ajax=false和immediate=true？事实上我把它当作ajax=true。我试着看看ajax=false是否会有任何不同，我会回答我自己的问题。似乎我意外删除了commandLink中的进程=“@this”<代码>

<p:commandLink  action="#ticketBean.editComment(com.commentId)}"                                                                                
            ajax="true" 
            value="Edit"                              
            process="@this" 
            update=":tabView:commentForm1" 
            immediate="true"/>
