Strange ComboBoxItem problem

Be sure your post includes:

UsingSmartGwt 2.4

I am fairly new to smart gwt.I am having problems with my comboBox.The problem is when I select "1" the window alerts "2" and when I select "2" the window alerts "1".But when I make my first selection the alert is blank.

I am trying to get the value of the comboBox.Am I using the wrong method?

myCombo.setTitle("How Many");  
myCombo.setType("comboBox");
myCombo.setValueMap("1", "2");  

myCombo.addChangeHandler(new ChangeHandler(){

	@Override
        public void onChange(ChangeEvent event) {
	String howMany = myCombo.getDisplayValue();
	Window.alert(howMany);
				
		}
     });

Wow I feel silly.That should have been an changedHandler.
