Problems with TextField in Window (jre 1.4.2)

Question

Hi,
I have a problem with the following code, which used to run o.k. on older vm's:
<CODE>
import java.awt.*;
import java.awt.event.*;
class TFTest extends Window {
     public TFTest(Frame frame) {
          super(frame);
          TextField tf = new TextField("Hello!");
          tf.setEditable(true);
          tf.requestFocus();
          add(tf);
     public static void main(String args[]) {
          System.out.println("Starting MAPP ParentGui...");
          Frame frame = new Frame("TFTest");
          TFTest mainFrame = new TFTest(frame);
          mainFrame.setSize(240, 320);
          mainFrame.setVisible(true);
</code>
The TextField doesn't seem to become editable whatever I change....
gr,
Peter

Two problems:
1. You must make parent Frame visible to make child Window focusable(see Javadoc for Window.isFocusable)
2. You request focus on the component before adding it to the top-level. Make sure you first add component, then request focus on it.
