So why does the triggerChangeNotification have no effect? It just
doesn't work.
It behaves per the specification in the documentation:
"Configures the receiver to post change notifications for a given
property if any of the properties specified in a given array changes.
[...]
Invocations of will- and did-change KVO notification methods for any
key in keys will automatically invoke the corresponding change
notification methods for dependentKey. The dependentKey will not
receive willChange/didChange messages to generate the notifications."
It doesn't *change* the dependent key itself (typically the dependent
key is recalculated in its get accessor).
