Thanks Alex for your suggestion. I tried to extend DefaultDataDescriptor but I
found ArrayCollection method easier not sure though if it is the better way to
do. However being new to Flex, it was good to explore new things.
I wrote following function which is based on Hpet's code given at
experts-exchange. Thought to share here if anyone needs in future.
private function buildNestedArray(flatArray:ArrayCollection,
parentId:int):ArrayCollection {
/* This recursive function takes a flat Array Collection and creates a nested
Array to implement Parent/Child hierarchy*/
var i:int = 0;
var nestedArray:ArrayCollection = new ArrayCollection();
var parents:ArrayCollection = new ArrayCollection();
for (i = 0; i < flatArray.length; i++) {
if (flatArray[i]["parentId"] == parentId)
parents.addItem(flatArray[i]);
}
if (parents.length < 1)
return null;
for (i = 0; i < parents.length; i++) {
var node:Object = parents[i];
var children:ArrayCollection = buildNestedArray(flatArray,
node["itemId"]);
if (children ) {
if (children.length > 0) {
node["children"] = children;
}
}
nestedArray.addItem(parents[i]);
}
return nestedArray;
}
