Hello Tracy, i made exactly this, extended and use this function:
public function setComboItem(combo:String,item:String):void{
for(var i:Number = 0; i < this[combo].dataProvider.length; i++)
{
if(this[combo].dataProvider[i] == item){
this[combo].selectedIndex = i;
}
}
}
But i'm think this is good think to be inside original comp.
