fixed that error by using import spark.components.ComboBox rather than its mx counterpart. But now on to a new error:1020: Method marked override must override another methodHere's a portion of the affected code (from the AutoComplete.as file):package myWidgets.ParcelNotificationWidget
{
import flash.events.Event;
import flash.events.FocusEvent;
import flash.events.KeyboardEvent;
import flash.net.SharedObject;
import flash.ui.Keyboard;
import mx.collections.ArrayCollection;
import mx.collections.ListCollectionView;
import mx.core.UIComponent;
import spark.components.ComboBox;

if(!usingLocalHistory)
tempCollection = value;The error has to be attributed to Flash Builder 4 since this code worked perfectly in Flex Builder 3 / SDk 3.3.....THANK YOU!!!!
