Steven,

Are you aware of kvc_accessor and kvc_array_accessor?

For example, at the start of a class definition, when I have a class  
attribute that I want to be accessed by key value coding, I put:

class Database < NSObject
   attr_accessor :last_update, :appartements, :arrondisements
   kvc_array_accessor :appartements, :arrondisements

Note that the attr_accessors are necessary because I also access these  
values through normal ruby programming.

kvc_array_accessor is used when the attribute to be accessed is an  
array, and kvc_accessor is used when it's just a normal attribute that  
you are accessing.

I know that I got bitten by this when doing raiseman.

Hope that helps,

Alli
