Java Swing: changing the text of a JLabel using an action listener

I have used an action listener on a JButton to change the text of a JLabel, although when the button is clicked nothing changes, any ideas what I'm doing wrong? The JLabel is called "crime description", here is the code in my action listener:

crimeDescription.setText(crime[randomInt].getCrimeName() + "\n" + crime[randomInt].getCrimeDescription());

crimeDescription.setVisible(true);

I just have a suggestion, not saying it will fix the problem but have you tried using the repaint() method after all of your changes.
