Description Dirk Wenke 2002-03-05 11:16:39 EST

This problem occurs since I switched from jdk1.3.1 to jdk1.4 (version 1.4.0-
rc). The problem occures when I run the main-method in the eclipse environment. 
It also occurs if I start from a console window while eclipse is running in the 
background. It only works properly if I shut down the eclipse environment and 
start from the console.

A short description of the example application :
I have a small JFrame with a JTextField and a JComboBox in it. I can
write into the textfield, but after I select something from
the combobox, I can edit the textfield no more. If I popup another
window in front of my frame and than return to my frame, I am able to
write again into the textfield.

Here is the code of the JFrame :


package test;

import javax.swing.*;
import java.awt.BorderLayout;

public class TestFrame2 extends JFrame {
	public TestFrame2() {
		super("TestFrame");
		setSize(200,200);
		getContentPane().setLayout(new BorderLayout());
		JComboBox comboBox = new JComboBox();
		getContentPane().add(comboBox, "South");
		comboBox.addItem("Test1");
		comboBox.addItem("Test2");
		JTextField tf = new JTextField();
		getContentPane().add(tf, "North");
	}

	public static void main(String[] args) {
		TestFrame2 frame = new TestFrame2();
		frame.addWindowListener(new java.awt.event.WindowAdapter() {
			public void windowClosed(java.awt.event.WindowEvent e) {
				System.exit(0);
			};
		}); frame.setVisible(true);
	}
}

Best regards
