List Events

• List can be single-select or multiple-select
• When an item is selected or deselected an event is posted
• When item is selected, event id is LIST_SELECT
• When item is deselected, event id is LIST_DESELECT
• handleEvent() in Component does not handle these events and returns false
• Need a custom handleEvent() instead
• Clean solution defines a new class SelectList with new constructors, overridden handleEvent() and new methods selected() and deselected()
