Alright, the error is invalid format for the data type. Am I to
assume that arrays can only derive to strings if they are inside a
dictionary?

Right. I've also tried:
[NSPropertyListSerialization dataFromPropertyList:filtersToArchive
format:NSPropertyListXMLFormat_v1_0 errorDescription:nil]
And that didn't work either, it simply return nil.
(filtersToArchive is an array). I haven't gone through and debugged
it yet with the errorDescription.
One of the requirements is the array has to be derived to a string,
as a plist is.

I'm trying to convert an NSArray to a string and read it back at
a later point. I call [myMutableArray description], store it
away, and then later try to recreate the array using [arrayString
propertyList].
However, upon trying to return an NSArray from the string I get:
2005-11-23 21:37:08.801 Catalyst[17518] XML parser error:
Unexpected character ( at line 1
Old-style plist parser error:
Expected terminating ')' for array at line 5
Here is the description string:

{
CIFilterName = CIHueAdjust;
inputAngle = 1.475182809936707;
inputImage = {CIImage [0 0 22 26]};
}
)
Is this a bug? I searched CocoaBuilder and found a message
detailing the exact same problem in 2001, but no one ever replied
to it.
Description is not meant as a way to serialize (aka archive) an
array.
Review NSCoding which NSArray implements...
