title: TextField not updating dynamically
body: <p>this is a really simple code in which text on a button is copied to a TextField.
  The code works fine but the TextField is not updating instantly on clicking the button.
  It updates only after i click on the TextField or when i drag the form not on pressing the button instantly.
  why is this happening,this behavior is unexpected.
  i am testing this code on a nokia 501 emulator which supports LWUIT.                  </p>
  
  <pre><code>           a = new Form("CALCULATOR")
                     final TextArea data = new TextArea();
             final Button ab = new Button("Some Value");
             ab.addActionListener(new ActionListener(){
  
              public void actionPerformed(ActionEvent arg0) {
                  // TODO Auto-generated method stub
  
                  data.setText(ab.getText());
  
              }
  
             });
             a.addComponent(ab);
             a.addComponent(data);
             a.show();
                     }
  </code></pre>
