Hi Jason,
This is a mistake in the documentation.
Thanks for pointing it out. I’ll file a documentation bug to ensure that
it gets fixed.
Thanks,

As Ralf said, I'm not sure what documentation you are
referring to. Let me be more specific and say the Flex Builder 2.0
documentation (as well as the LiveDocs at http://livedocs.macromedia.com/flex/2/langref/Array.html).
Does that help clear things up?

I read the help, and it pretty well spells out that you send optional
arguments in the sample, but I could see where it states "[,
value:Object] that someone could find that confusing.
The sample at the bottom of the help file shows exactly what you ended
up finaly doing:
var myFurniture_array:Array = new Array("couch", "bed", "desk", "lamp");
trace( myFurniture_array.splice(1,0, "chair" ) ); // Displays empty array.
trace( myFurniture_array ); // displays couch,chair,bed,desk,lamp

Either there is a bug in Array.splice, or the
documentation is off.
>From the help:
Example
The following code creates the Array object vegetables
with the elements [spinach, green pepper, cilantro, onion, avocado] .
The splice()
method is then called with the parameters 2 and 2, which assigns cilantro
and onion
to the spliced
array. The vegetables
array then contains [spinach,green pepper,avocado].
The splice()
method is called a second time using the parameters 1, 0, and the spliced
array to assign [spinach,cilantro,onion,green pepper,avocado] to
vegetables.
var vegetables:Array = new Array("spinach",
"green pepper",
"cilantro",
"onion",
"avocado");
var spliced:Array = vegetables.splice(2, 2);
trace(vegetables); // spinach,green pepper,avocado
trace(spliced); // cilantro,onion
vegetables.splice(1, 0, spliced);
trace(vegetables); // spinach,cilantro,onion,green pepper,avocado
However, this is not the case. When you pass an array as the third
argument to splice, it adds the target ARRAY to the original array. It
does not insert the VALUES in the target array.
if you add
for each (var o:Object in vegetables)
trace(typeof(o), o.toString());
you will get:
string
spinach
object cilantro,onion
string green pepper
string avocado
So, is this a bug or intended behavior? I could see how it could go
either way. However, it seems the example in the documentation should be
fixed. I'm thinking it was intended that a passed-in array would be
disassembled and its components added. Otherwise, why say "one or
more comma-separated values, or an array, to insert into the array"?
Singling out array makes no sense, as it would be treated like any other value
passed in.
