Java SE (Java Platform, Standard Edition)

Hello everyone,

I have written my own class that shows a customized confirm dialog (code is pasted below). I need to be able to tell whether the user clicks "YES", "NO" or "CANCEL".
My main app has a panel with a JButton "Start System". When this button is clicked, the following code instantiates OperatorConfirmDialog:

	public void startNetwork(){
		confirmDialog = new OperatorConfirmDialog("Are you sure you want to start the network?");
		System.out.println("WE MADE IT TO HERE");//problem we do not get to here until confirm dialog acked
	}

I referred to the examples for JOptionPane given at:
http://java.sun.com/j2se/1.5.0/docs/api/index.html
for examples but it doesn't seem to be working for me.

Here is the code for OperatorConfirmDialog

public class OperatorConfirmDialog extends JFrame {
	JOptionPane pane;
	public OperatorConfirmDialog(String message){
		pane = new JOptionPane();
		this.setDefaultLookAndFeelDecorated(true);
		this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		this.getContentPane().setLayout(new BorderLayout());
		pack();
		//pane.getSelectionValues()
		pane.showConfirmDialog(this, message, "Confirm", JOptionPane.YES_NO_CANCEL_OPTION);
		Object selectedValue = pane.getValue();  //problem here
		if(selectedValue == null){
			//do nothing...they just killed window
		}else {
			for(int counter = 0, maxCounter = pane.getOptions().length; counter < maxCounter; counter++){
				if(pane.getOptions()[counter].equals(selectedValue)){
					//do something
				}
			}
		}
		this.dispose();
	}
	
	public JOptionPane getPane(){
		return pane;
	}
	
	public static void main(String[] args) {
		OperatorConfirmDialog dialog = new OperatorConfirmDialog("Please enter a valid username.");
	}
}

I put a break point at the line:
if(selectedValue == null){

When I run the debugger, confirmDialog prompts me to click "YES", "NO" or "CANCEL". I click "YES" and then arrive at the breakpoint. But, selectedValue doesn't seem to have the right value....the debugger says its value is "uninitializedValue" (literally). Any ideas?

Thanks!
