Flex: ArrayCollection children returns null

Question

I have an ArrayCollection with following structure (when viewed in debug mode):

[0]
- [0]
-- src
- [1]
-- src

src is the path to an image.

I need to get all of the src's out of the arraycollection. However because of the first (unnamed) node i can't take them in.

I've tried ArrayCollection[0].children and save the result in another ArrayCollection, however the new ArrayCollection has 2 Objects in it but no 'src'. There are just 2 null objects

firstArrayCollection is filled with the data as described above.

secondArrayCollection.addItem(firstArrayCollection[0].children);

when viewing the content of secondArrayCollection i see following structure (and data):

[0] null
[1] null

Answer 1

try

var i:int = 0;
var myNormalArray:Array = new Array();

//loop through collection
for each (var child:* in myArrayCollection)
{
  //do what you want with the child
  myNormalArray[i++] = child;
}

This will get all of the objects out of the collection into a normal array where they can be refered by their index. If you look at an array collection it has no concept of length so the index cannot be a index it has to be a key.

or just do this thinking about it (although i've never done it)

var myArray:Array = myArrayCollection.toArray();

hope this helps

Second Attempt !!!!!!

var pathArray:Array = new Array();
var i:int = 0;
for each (var child:* in myArrayCollection)
{
  for each (var pathObject:Object in child)
  {
    pathArray[i++] = pathObject.src;
  }
}

this should work, i haven't test it though
