Departments contain one or more Employees and Employees have one
manager(a relation to an employee).
In IB I have an ArrayController of Departments and an ArrayController
of Employees of the selected Department. This works fine.
What I want is an ArrayController of Managers of the selected
Department. I have tried binding to the Departments controller with
the keyPath email@hiddener, but I get this
error:
[<_NSFaultingMutableSet 0x3693b0>
addObserver:forKeyPath:options:context:] is not supported.
Key path: manager' that raised during posting of delayed perform with
target 397740 and selector 'invokeWithTarget:'
Can someone please explain to me why this wont work? I have read all
the Key-Value programming guides and the bindings guide, if they say
why this shouldn't work I missed it. Is it that key-value operators
don't work with CD sets?
Thanks in advance for any insight provided.
Brian
