Hi,
I add the observer as follows:
[[DigiDevicesManager sharedDigiDevicesManager] addObserver:self
forKeyPath:@"digiDevices" options:NSKeyValueObservingOptionOld context:nil];
It's superclass is NSObject and I did not disable automatic notifications.
If mutate the array (from inside the observed object) with [self
{will/did}change..] then everything works fine.
Regards,
Remco Poelstra
