我是jsf Primefaces的初学者。我有primefaces数据表的问题。 当我在对话框组件中选择要查看的行时，不会显示任何内容。

@EJB
PointserviceFacade bean;
List<String> Pointservices;
List<Pointservice> listePS;
private Pointservice selectedPointservice;
/**
* @return the Pointservices
*/
public List<String> getPointservices() {
listePS = bean.findAll();
return Pointservices;

/**
* @param Pointservices the Pointservices to set

public void setPointservices(List<String> Pointservices) {
this.Pointservices = Pointservices;

/**
* @return the selectedPointservice

public void delete() {
bean.remove(selectedPointservice);
}
public void editps(){

}
我正在使用primefaces 3.5。 你能帮助我吗？感谢。

你犯了一些错误。首先由@tiny评论“ 其中ListerPointSBean中的test（）方法在actionListener中指定的 “
你的bean中的创建一个test（）方法，你可以在其中设置你想要在对话框中显示的属性的值....
调用对话框的正确方法是
oncomplete="PF('psDialog').show()"

在ajax rowSelect事件中，您需要在p：dialog中更新h：panelGrid。
<p:ajax event="rowSelect" update=":myform:display" oncomplete="psDialog.show()"/>
