Swing/AWT/SWT :: How To Fill Text Fields With Selection From JList

I have an addressBook GUI where I have a JList that populates with the contacts names, and once I double click a contacts name I'm wanting to fill the textfields with the contacts corresponding data.

ex) ContactType: Family (enum), Name: Zoidberg, Address: 111 Space Drive, City: New York City, etc...

I've got it to where I select open from the JMenu, it populates the JList, but once I select a contacts name, all the textfields are populated, but only with the contacts name

ex) Name: Zoidberg, Address: Zoidberg, City: Zoidberg, etc....

What am i doing wrong here, and how can i fix it to where it fills out the correct data?

Here's my code so far:

public class AddressBookGUI extends JFrame {
private final int WIDTH = 450;
private final int HEIGHT = 300;
private JLabel currentlySelected;
private JTextField contactTypeTextField;

[code]...

I'm certain the logic is messed up near the end where i set all text fields to the index, because no matter what field i want to fill it's at it's going to set it to whatever index I select, but I don't know how to fix it.
