Re: No text on a JButton after some action has been installed

I've got the following code

package test;

import java.awt.event.ActionEvent;

import javax.swing.AbstractAction;
import javax.swing.JButton;
import javax.swing.JFrame;

public class BtnBug extends JFrame {

    public static void main(String[] args) {
    final BtnBug bb = new BtnBug();
    JButton jbut = new JButton("New Dialog");
    jbut.setAction(new AbstractAction(){
        public void actionPerformed(ActionEvent e) {
        }});
    bb.add(jbut);
    bb.pack();
    db.setVisible(true);
    }
}

For some reason the text on the button is not displayed (or set to
empty string)?
