I'd like to find the largest integer value of one of my entity fields,
stored in an NSTreeController. Is this possible? I'm trying to use
"@max", but getting back null on every variant:
NSNumber* maxVal = [mItemsController valueForKeyPath: @"@max.number"];
I also tried with "arrangedOBjects".
I can't even figure out how to manually iterate the objects. Is there
a way?
TIA,

Rick
