请教高手：我在Jbuilder下做了一个bean控件，内容就是继承Jpanel，共两个panel组成，panel1和panel2，japenl2放在一上面，在使用该bean控件时，我在开发环境里放了一个按钮在panel2上，为何不能显示，只能鼠标点击了该按钮在出现，不知该如何实现该bean；
我的代码如下：
package mybean;

import java.awt.*;
import javax.swing.*;
import com.borland.jbcl.layout.*;
import javax.swing.border.*;
import java.io.*;
import java.awt.event.*;
import java.util.*;
import javax.swing.event.*;
