Primefaces表單值不顯示

我有primefaces dataTable我想要編輯的行。我確實提交了該行的ID，並將其顯示在要編輯的面板中。使用相同的對象，如果我使用h：outputText輸出值，我可以看到這些值。 p：inputText不顯示值。如果我使用瀏覽器重新加載按鈕刷新頁面，表格值顯示得很好。以下是我的代碼的精簡版。Primefaces表單值不顯示

型號

@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; 

}

控制器

@Named("ticketBean") 
@Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS) 
public class TicketBean implements Serializable 
{ 
private Ticket ticket = new Ticket(); 
private Comment comment = new Comment(); 
/** 
    * getters & setters 
     */ 
    public void editComment(long commentId) 
    { 
     for (Comment editComment: ticket.getComment()) 
     { 
      if (editComment.getCommentId().longValue() == commentId) 
      { 
       this.comment = editComment; 
       changeButtonValue("tabView:commentForm1:submitAddComment", "Save");    
       break; 
      } 
     } 
    } 
}

XHTML

<h:form prependId="false" id="commentForm1"> 
    <p:panel id="panelComment"> 
    <h:outputText value="#{ticketBean.comment.comment1}"/> 
    <p:inputTextarea styleClass="textarea" value="#{ticketBean.comment.comment1}" 
         rows="4" 
        cols="60" 
        maxlength="255" 
        counter="counter2" 
        counterTemplate="{0} characters remaining." 
        id="comment1"

<h:outputText id="counter2" style="font-size:8pt;" /> 
<p:commandButton id="submitAddComment" value="Add"

             ajax="true" 
             style="font-size:11pt;" process="panelComment" 
             update=":tabView:commentForm1" /> 

<p:dataTable id="ticketCommentsList" var="com" 
     value="#{ticketBean.ticket.comments.toArray()}" 
     paginator="true" dynamic="true" rows="10" 
     paginatorPosition="bottom" lazy="true" 
     paginatorAlwaysVisible="false" widgetVar="projTable" 
     paginatorTemplate="{RowsPerPageDropdown} {FirstPageLink} {PreviousPageLink} {CurrentPageReport} {NextPageLink} {LastPageLink}" 
           rowsPerPageTemplate="10,15,20" styleClass="prime-datatable"> 

    <p:column id="comment1" headerText="Comment"> 
      <h:outputText value="#{com.comment1}" /> 
     </p:column>        
    <p:column> 
     <f:facet name="header">Edit</f:facet> 
    <p:commandLink action="#{ticketBean.editComment(com.commentId)}"            
         ajax="true" value="Edit" 
         update=":tabView:commentForm1" 
         immediate="true"/> 
     </p:column> 
    </p:dataTable> 
</p:panel> 
</h:form>

爲什麼會<h:outputText value="#{ticketBean.comment.comment1}"/>打印出來的值不過 <p:inputTextarea value="#{ticketBean.comment.comment1}"/>不顯示值？

感謝您的幫助。

爲什麼AJAX = false，並立即=真的嗎？ – Leo

其實我把它當作ajax = true。我試圖看看如果ajax = false會產生任何影響 – user3520171

我會回答我自己的問題。看到我像意外刪除了commandLink中的過程=「@ this」。 '' – user3520171

好像我不小心刪除了porcess = 「@這個」我曾在commandLink

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