>             Project: Apache Flex
>          Issue Type: Bug

>
> Steps to reproduce:
> 1.Create an ArrayCollection with multiple items.
> 2.Apply a filter function that filters all items out.
> 3.Use the addAll method to add multiple items to the original collection while it's filtered.
>  
>  Actual Results:
> A RangeError saying "Index '1' specified is out of bounds."
>  
>  Expected Results:
> No error and items to all be added to the source list.
>  
>  Workaround (if any):
> Create a for each loop that uses addItem instead.
> The problem seems to lie in the ListCollectionView.addAllAt method.  It loops over the
addList using a for loop and attempts to addItemAt with each one, incrementing the index it
adds at.  addItemAt throws a RangeError if the index is greater than the length (which will
be 0 if the filter applies to all items in the collection) so after the first item is added
at index 0, the next item is attempted to be added at index 1 which is greater than the length
of 0 and a RangeError is thrown.
> Found in the Flex SDK 4.1 release build 16076
