OK Ignore what I just said.
Have you looked at the JavaDocs? If not then I recommend that you download them, they're an invaluable source of information. Everything I'm about to tell you is straight from the JavaDocs, I've no experience in using ItemListeners.
The Javadocs say:
addItemListener
public void addItemListener(ItemListener aListener)
Adds an ItemListener.
aListener will receive one or two ItemEvents when the selected item changes.
Then JavaDoc from ItemEvent:
public class ItemEvent
extends AWTEvent
A semantic event which indicates that an item was selected or deselected. This high-level event is generated by an ItemSelectable object (such as a List) when an item is selected or deselected by the user. The event is passed to every ItemListener object which registered to receive such events using the component's addItemListener method.
What you are seeing is an ItemEvent.SELECTED
and a ItemEvent.DESELECTED. I don't know the order in which you'll get them.
