Sorry if I missed available resources to answer this question.
I have a binary attribute in one of my core data entities called,
"selectionIndexPaths". In IB I bound a tree controller with this key
path to the selection of an array which contains the entities. I
also used the NSUnarchiverFromData value transformer in IB. However,
when ever I save I get this message, "-encodeInt:forKey: only defined
for abstract class. Define -[NSArchiver encodeInt:forKey:]! " I am
not sure what this means, where do I need to define it? I thought
NSIndexPath conformed to the NSCoding protocol?
