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'?
Yes, in exactly the same manner as my unitCost accessor method in
EffectUnit. I figured if I was on the right track it should be
right. The weird thing in the message is the error states that
EffectUnitManagedObject has the valueForUndefintedKey, but the
totalCostOfUnits is the accessor in BudgetManagedObject. I've
looked through IB for bindings that are looking for the
totalCostOfUnits in EffectUnitManagedObject but can't find anything.

Figured it out. I had set EffectUnit as a child of Budget, thinking
database parent/child and not o-o parent/child.
of course other things are now broken but that's another post if i
can't figure it out myself...
thx!
