Use only unique values as combo box data provider.

Question

I have an array collection of objects each of which has a
property I
will simply call 'name'. Let us say that this array
collection contains
a list of objects with the following name values
['George','Fred','George','Ron','Bill','Charlie','Bill','Bill','Percy'].
I would like to use these names as the data provider of a
combo box, but
without the duplicates. What would be the easiest way to
distill this
down to an array of unique values to use as this combo box's
data
provider in Flex?
The original array collection was the result of an remote
object call to
a cfc that returned a record set from a data store. Is it a
better
option to create a new function in this cfc that returns the
unique list
I desire, or can I do this easily inside the Flex code since
I already
have the complete list?
TIA

Untested:
var aData:Array =
['George','Fred','George','Ron','Bill','Charlie','Bill','Bill','Percy'];
var oCheck:Object = new Object():
var aUnique:Array = new Array()
var sValue:String
for (vari:int=0;i<aData.length;i++) {
sValue = aData[ i ];
if (!oCheck[sValue ]) { //is this a unique value?
oCheck[sValue ] = true; //put this value in the check object
aUnique.push(sValue)
Note: if the values contain illegal property name values, yo
would need to modify this.
