I wouldn't give a Sort and a compareFunction - what's the point ? Just
have one or the other.
Either way, this wont empty your ArrayCollection. If you dump it out
before and after
var grunner:ArrayCollection
along with where ever it came from, are your *sure* it isn't being
populated by an empty array, null object, failed cast etc. ?
Failing that, make a standalone example we can all build.

Hi.
I am very very new to Flex.
I created this thread for sorting in Java
http://stackoverflow.com/q/15091732/37298
However, I am now trying to do the same thing in ActionScript.
I have a Bindable ArrayCollection with Objects that looks like this
Code.code : F
Code.label: Foo
Code.description: The Foo description
Then I want to sort exactly as specified in the stackoverflow site.
I have around 10 of them which I need in a particular order. I have them
defined in an array.
Based on the stackoverflow question and some googling, I have come up with
the following:
private function myCompare(a:Object, b:Object, fields:Array = null):int {
if (mostUsed.contains(a.code) && mostUsed.contains(b.code)) {
return fields.getItemIndex(a) - fields.getItemIndex(b);
}
if (mostUsed.contains(a.code)) {
return -1;
}
if (mostUsed.contains(b.code)) {
return 1;
}
var s:Sort = new Sort();
s.fields = fields;
var f:Function = s.compareFunction;
return f.call(null,a,b,fields);
}
private var mostUsed:ArrayCollection = new ArrayCollection(["F", "A", "B",
"FTR", "HIS", "KEB", "LEG", "MED", "MER", "PEN", "PEO", "PER", "PIN",
"PUR", "REF"]);
var grunner:ArrayCollection = //getting collection
grunner.sort.fields = [new SortField("code")];
grunner.sort.compareFunction = myCompare;
grunner.refresh();
But it doesnt work. Any clues?
My collection returns empty.
