How to assign an Associative array to a list component in FLEX 4.6

Question

I would like to print the values of my associative array in a list. Im doing this, but i think the IList class uses the common index [0]..[n] to print the elements (im not sure of this)

my code(example):

private var arr = new Array();
private var arrList: new ArrayList(arr);


private function init()
{
  arr["hello"]="world";
  list.dataProvider = arrList; //the component was instanced before
}

I have been debbugging and the arrList updates the info with elements of arr, but list component dont show anything.

Any suggestion? Thanks.

dataProvider appears to accept key:value pairs as label and data object entries pushed to an array which is mirrored the actual List. Personally, I prefer to roll with my own list class, so I'm not speaking from List object experience. See Adobe's documentation for List.dataProvider for more info.

private var foo:Object = {
    "hello":"world",
    "apple":"pie",
    "orange":"juice"
}

var dpArr:Array = [];
list.dataProvider = dpArr;

for (var key:String in foo) {
    dpArr.addItem({label:key, data:foo[key]});
}
