Description
The FPONotifyObservers method is the central notification mechanism that calls the FPOObservedChanged method on all attached observers.
This method is used internally by all other notification methods and can be called directly for custom notification scenarios. The operation parameter specifies the type of change that occurred.
The method iterates through the observer list in reverse order to handle observers that might detach themselves during notification.
