我的问题既简单又困难。

我想在我p:dialog里面显示一些信息。所以我使用我的面板网格来做到这一点。但它不显示信息，我不知道为什么。所以这是我的页面和我的 bean 的代码；）

（我使用的是 PrimeFaces 4.0、Mojara 2.1.6）

 package ma.corporate.bean;

    import java.io.Serializable;
    import java.util.List;
    import javax.faces.bean.ManagedBean;

    import javax.faces.bean.SessionScoped;

    import ma.corporate.facade.MessageFacade;
    import ma.corporate.model.Message;

    @ManagedBean(name = "messageBean")
    @SessionScoped
    public class MessageBean implements Serializable {
    /**
     * 
     */
    private static final long serialVersionUID = 1L;
    private MessageFacade messageFacade;
    private List<Message> messages;
    private Message message;
    private static int cpt=0;
    //private Message message2;

    public MessageBean() {
        // messageFacade = new MessageFacade();
        // messages = messageFacade.Lister();
        /*
         * if(messages==null) System.out.println("null"); else
         * System.out.println(messages.get(0).getTextMessage());
         */
        //message2=new Message();
        message = new Message();
        cpt++;
    }

    public List<Message> getMessages() {
        // messages = messageFacade.Lister();
        messageFacade = new MessageFacade();
        messages = messageFacade.Lister();
        return messages;
    }

    public void setMessages(List<Message> messages) {
        this.messages = messages;
    }

    public Message getMessage() {
        return message;
    }

    public void setMessage(Message message) {
        this.message = message;
    }

    public void save() {
        messageFacade.enregistrer(message);
    }

    public void Supprimer(Message message) {
        messageFacade.supprimer(message);
        messages = messageFacade.Lister();
    }

    public void init(Message message) {
        //this.message.setEmail("aaaaaaaaaaaaaa");
        //this.message.setNomComplet("bbbbbbbbbbbbbbbb");
        //this.message.setTelephone("343232");
        this.message = message;
        System.out.println(this.message.getNomComplet());
        System.out.println(cpt);
    }

}

由于我想发布它时出现错误，我无法制作我的 html 页面的代码。

看起来像一个更新问题。bean 从 xhtml 页面获取值？如果他得到它，请尝试替换这两行：

<p:commandLink onclick="PF('dlg3').show();" process="@this" actionListener="#{messageBean.init(message)}">

<p:dialog header="Message" widgetVar="dlg3" showEffect="explode" hideEffect="bounce" resizable="true">

经过 ：

<p:commandLink onclick="PF('dlg3').show();" update=":form1:dlg3" process="@this" actionListener="#{messageBean.init(message)}">

<p:dialog header="Message" id="dlg3" widgetVar="dlg3" showEffect="explode" hideEffect="bounce" resizable="true">
