Hey Matt,
The Flex reference will definitely need to be updated then. Should I
create a report, or are you passing it along to the right person/team?

Well, it looks like either the documentation is wrong, or the code.
The ListCollectionView class has the following method defined:
public function addItemAt(item:Object, index:int):void
{
if (index < 0 || !list || index > length)
throw new
RangeError(StringUtil.substitute(resourceOutOfBounds, index));
var listIndex:int = index;
//if we're sorted addItemAt is meaningless, just add to the end
if (localIndex && sort)
{
listIndex = list.length;
}
list.addItemAt(item, listIndex);
}
Makes it very clear that the list isn't grown when the index exceeds
the length of the list. :-)
Anyone concur? If so, I'll submit a report to Adobe.

It seems that there is a problem with the ListCollectionView class when
using it with an ArrayCollection. Using the addItemAt method produces an
index out of bounds error when an item is added with an index that is
beyond the length of the collection.
However, the Flex Reference states that:
"If the list is shorter than the specified index, it will grow to
accommodate the new item."
Is this a confirmed bug, or am I overlooking something?
Here is some test code to check it out:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml
<http://www.adobe.com/2006/mxml>"
creationComplete="initApp()"
layout="vertical">
<mx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
private var collection:ArrayCollection = new ArrayCollection();
private function initApp():void {
var newObject:Object = new Object();
newObject.test1 = "test1";
newObject.test2 = "test2";
collection.addItem(newObject);
newObject = new Object();
newObject.test1 = "test3";
newObject.test2 = "test4";
collection.addItemAt(newObject, 3);
}
]]>
</mx:Script>
</mx:Application>
Anyone run into this too?
Jurgen
