Modifying Array position with IViewCursor

Question

I have array print with command
Alert.show(''+ObjectUtil.toString(arrColl));
(mx.collections::ArrayCollection)#0
filterFunction = (null)
length = 4
list = (mx.collections::ArrayList)#1
length = 4
source = (Array)#2
[0] (Object)#3
2008-03 = "1473"
2008-03p = "40,19"
desc = "Usuários únicos"
[1] (Object)#4
2008-03 = "1476"
2008-03p = "-16,80"
desc = "Novos usuários"
[2] (Object)#5
2008-03 = "53114"
2008-03p = "39,25"
desc = "Sessões"
[3] (Object)#6
2008-03 = "45"
2008-03p = "-97,78"
desc = "Tarifação"
uid = "8B1A7D6D-62D1-C9BF-85DD-C538F40ED10D"
sort = (null)
source = (Array)#2
I would like to modify the position of the Array, moving the
last key for the beginning.
thus:
[0] (Object)#3
desc = "Usuários únicos"
2008-03 = "1473"
2008-03p = "40,19"
[1] (Object)#4
desc = "Novos usuários"
2008-03 = "1476"
2008-03p = "-16,80"
[2] (Object)#5
desc = "Sessões"
2008-03 = "53114"
2008-03p = "39,25"
[3] (Object)#6
desc = "Tarifação"
2008-03 = "45"
2008-03p = "-97,78"
my code source, but is not functioning. some tip of the
error?
/code]
//Recebi o resultado e guarda em um array devido
ordenação
var arrColl:ArrayCollection = new ArrayCollection(event.data
as Array);
Alert.show(''+ObjectUtil.toString(arrColl));
if (! runBefore) {
runBefore=true;
for (var i:int=0; i < arrColl.length; i++)
// Get an IViewCursor object for accessing the collection
data.
var myCursor:IViewCursor=arrColl
.createCursor();
// Get the original collection length.
var oldLength:int=arrColl.length;
myCursor.seek(CursorBookmark.LAST);
// The cursor is initially at the first item; delete it.
var removedItem:Object=Object(myCursor.remove());
// The cursor is at the (new) first item;
// move it to the firs item.
myCursor.seek(CursorBookmark.FIRST, 0);
// Add removedItem as the first item.
myCursor.insert(removedItem);
var sort:Sort = new Sort();
arrColl.sort=sort;
// Refresh the collection view to apply the sort.
arrColl.refresh();
//Guarda na variavel o array
dgReport.dataProvider = arrColl;
