I agree that you are probably better doing the backend search, but if you need
to do it in your app here's the proper way to sort. You just missed declaring a
sort as a new object (then since you didn't have an object you were trying to
apply sortfields to an AC) and then you apply that new sort to your AC.
private function private function userHandler(event:ResultEvent):void{
acUsers = evt.result.rows.row;
var sort:Sort = new Sort();
sort.fields = [new SortField("usraccount",true)];
acUsers.sort = sort;
acUsers.refresh();
}
