We had this question on the flexaussie mailing list a couple of days ago.
There is an example in the docs that works:
import mx.collections.ArrayCollection;
import flash.utils.ByteArray;
private function clone(source:Object):*
{
var myBA:ByteArray = new ByteArray();
myBA.writeObject(source);
myBA.position = 0;
return(myBA.readObject());
}
private function init():void{
var data:Array = [{name:"one",value:1},{name:"two",value:2}];
var a:ArrayCollection = new ArrayCollection(data);
var b:ArrayCollection = clone(a);
b.getItemAt(0).value = "foo";
trace(a.getItemAt (0).value);
trace(b.getItemAt(0).value);
}
Seems to work ok.

I think that will give you two ArrayCollections which share the same
data items. For example, if you do
arrayCollection.setItemAt("foo", 0);
trace(arrayCollection2.getItemAt(0));
you'll probably get "foo".

No loop required. Just create a new array collection with the source of
the old array collection.
arrayColletion2 = new ArrayCollection(arrayCollection1.source);

Hey guys,
is there a way to "copy" an ArrayCollection instead of referencing it
by ArrayCollection1 = ArrayCollection2;???
I can't believe that there is no way to do this, except cophying each
value in a loop.
Thanks,
Mane
