[flexcoders] Re: Filters on dynamic array collection.

[cbaray]

Sorry - took me a while to get around to building a small example app.
 But thanks for the LCV solution - works like I expected the
ArrayCollection filter to work.

So, this will filter the list after it gets to 5 items and then once
it's filtered, the addItemAt calls no longer work.

Thanks - 
cris.
