47 47  It's in the docs, but NSArray's implementation of KeyValueCoding is not really what I was expecting. To get an object at a specific numeric index of an NSArray, you'd use the

63 63  It turns out that calling valueForKey on an array is the same as calling valueForKey for each element of that array. So if you have an NSArray of Users, calling valueForKey("email"); will return an NSArray of email addresses. calling valueForKey("documents"); will return an NSArray of NSArrays containing document objects. In hindsight (and from looking at the way WOBuilder handles key paths for arrays) this is kind of obvious. But I think the real lesson here is that it is easy to ignore the docs towards the end of an alphabetical page...
