Liste.java

package pro;


import java.util.ArrayList;
import java.util.List;

import javax.annotation.ManagedBean;
import javax.annotation.PostConstruct;
import javax.faces.bean.SessionScoped;

@ManagedBean
@SessionScoped
public class Liste  {

    private  List<Veri> dizgi=new ArrayList<Veri>();

    public List<Veri> getDizgi() {
        return dizgi;
    }

    public void setDizgi(List<Veri> d) {
        this.dizgi = d;
    }


    public Liste(){};
    @PostConstruct      
    void  Listele(){

         dizgi.add(new Veri("B-8821083","20150513",-1,-29));
         dizgi.add(new Veri("B-8821083","20150521",46,4.718));
         dizgi.add(new Veri("B-8821083","20150602",-5,-455));
         dizgi.add(new Veri("B-8821083","20150623",-4,-305));
         dizgi.add(new Veri("B-8821083","20150506",7,0));
         dizgi.add(new Veri("B-8821083","20150612",1,0));
         dizgi.add(new Veri("B-8821083","20150615",50,4.602));





    }








}

这是代码，当我运行此代码时。它说

未找到任何记录。

任何想法，这里有什么问题？我试图将List两个属性打印为列。它没有给出错误。只显示没有找到记录。但实际上存在很多元素。有一个veri类。它提供了诸如Agent_Code和date以及getter和setter方法等属性。

没有记录发现primafaces数据表
