Question: 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. 

```
           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();
                   }

```

Answer: 
After setting the text in the textfield repaint it. This may work 

```
  data.setText(ab.getText());
  data.validate(); or data.repaint();

```
```
          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()); // You should not use this

                // Use this instead
                  data.setText(ab.getActionCommand());

            }

           });
           a.addComponent(ab);
           a.addComponent(data);
           a.show();
                   }

```
