Question

我正在使用PrimeFaces 4.0 / Mojarra 2.2库的eclipse kepler，JSF 2.2。

实际上有两个问题：

无论我做什么，我仍然会收到此服务器消息。

（（javax.el.PropertyNotFoundException：/Order.xhtml @ 28,76 value =＆＃34;＃{kk.refugee.id}＆＃34;：目标无法到达，＆＃39;难民＆＃ 39;返回null）） 如果我删除隐藏的输入文本脉冲，则会弹出消息“材料”。 selectOneMenu用于

我没有机会参加考试：（（这个javascript代码是否正确，将一个组件的值复制到另一个组件。）

这些是我的xhtml文件和java calsses。 thx in advanced。

的 kk.java

package khldqr.beans;

import javax.faces.bean.ManagedBean;

@SessionScoped

public class kk {

    private RefugeeMan refugee;

    public void AidsSpecialInsert(){

        System.out.println(refugee.getId());
        System.out.println(refugee.getMaterial());
        System.out.println(refugee.getId2());
    }

    public kk() {
        // TODO Auto-generated constructor stub
    }

    public RefugeeMan getRefugee() {
        return refugee;
    }

    public void setRefugee(RefugeeMan refugee) {
        this.refugee = refugee;
    }
