JList selection questions

I want to open a new frame when a selection is made from a JList and send the value in the selected cell in the JList to the new frame.
How do I set up a listener to do that without the code (listed below) producing two rows and also two new windows, as shown below

public void valueChanged(ListSelectionEvent e) {
if (e.getValueIsAdjusting()) {
if (theList.isSelectionEmpty()) {
} else {
if (isDone == false) {
int index = theList.getSelectedIndex();
System.out.println(index + " " + theList.getSelectedValue());
Object theValue = theList.getSelectedValue();
String pString = theValue.toString();
Out2SecondGui newgoo = new Out2SecondGui((String) "two");
isDone = true;

Don't know why you're getting two calls... the e.getValueIsAdjusting() call should filter out the "deselected" event... perhaps you are registering two event listeners on your list?

This code is working out fine for me...

It is sorta covered in the JavaRanch Style Guide.
