Well for further reference what i ended up doing was:
- Created a bogus Property "cellData" that is a function returning self
- The updated thread just used the pair willChange and didChange "cellData"
and it works
I tried the other way with the keyPathsForValuesAffectingValueForKey method,
but he wasn't called (Im using RubyCocoa might be the reason =).
