Needless to say I get an error. I don't think the effectUnits part
is right, although it is the name of the relationship? If this is
right, how does the program know to run all the objects in the
relationship?
This should be fine.
Here is the error: "NSRunLoop ignoring exception
'[<EffectUnitManagedObject 0x31f320> valueForUndefinedKey:]: this
class is not key value coding-compliant for the key
totalCostOfUnits.' that raised during posting of delayed perform
with target 3a4890 and selector 'invokeWithTarget:"
Have you implemented an accessor method called 'totalCostOfUnits'?
