In XMLListAdapter, addItemAt() we see this after the first addItem()
source[0] = length > 0 ? item + source[0] : item;
this effectively sets source[0] to the unchanged item... and the parent doesn't
change. so, remember, item still has the original XMLList as a parent
So, at this point, source[0].parent() is the original XML list... not source.
After this first item is added, the XMLListCollection has 1 item in it and the
mainXML still has 3 items. All is well.
... the loop continues
After the second addItemAt() we get into XMLListAdapter again, however, since
there is already an item in the list we are funneled into a different condition:
source[index - 1] += item;
So, we take source of index-1, which is the first node... and we add item to
it... but the first node's parent is the _original_ XMLList (mainXML).
After this line executes, the original XMLlist now has 4 items, including two
copies of item #2.
We, of course, do this all again, and now the mainXML has 5 items including two
copies of item #2 and two copies of item #3.
...
Now, it works in the index cases.... well cause it doesn't and it's a false
reading:
for (var i:int=0; i < mainXML.item.length; i++)
{ some.addItem(mainXML.item[i]); }
So, the mainXML.item.length evaluates to 0. It never runs the loop and hence,
the original XMLList is unchanged. That's because length is a function on an
XMLList, you meant: mainXML.item.length() which shows the same problem.
