我的问题既简单又困难。
我想在我的p:dialog里面显示一些信息。所以我用面板网格来做。但是它没有显示信息，我不知道为什么。这是我的页面和bean的代码;)
(我使用的是PrimeFaces 4.0, Mojara 2.1.6)
MessageBean
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);
}
}
我不能使我的html页面的代码，因为一个错误，当我想要发布它。

看起来像是更新问题。bean从xhtml页面获取值吗?如果他得到它，试着替换这两行:
<p:commandLink onclick="PF('dlg3').show();" process="@this" actionListener="#{messageBean.init(message)}">
<p:dialog header="Message" widgetVar="dlg3" showEffect="explode" hideEffect="bounce" resizable="true">
<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">
