[flexcoders] Help on sorting an ArrayCollection then adding an item to the top

[Mark]

I'm trying to sort an arrayCollection that is the dataProvider for a 
comboBox.  But I also need to add an item to the top of the 
list "Select One".  Everything I've tried always sorts that object 
as well.  Is there a way to exclude something from a sort or am I 
just doing this completly wrong?  Here's what I have?


var sort:Sort = new Sort();
sort.fields = [];
sort.fields.push(new SortField("title",true));
nameCollection.sort = sort;
nameCollection.refresh();
//
// add new item to the top
//
var sItem:Object = new Object;
sItem = {title:"Select One"};
nameCollection.addItemAt(sItem,0);
//nameCollection.refresh();


Thank You,
Mark
