Does anyone know how to capture failed mapping event?

[jervin]

So I know there is a RKObjectMapperDelegate which if adopted would allow me to be notified of failed mappings. But I am not sure how to get access to the actual ObjectMapper when the mappings happen.

Here is how I make my requests.

- (void) fetchThingsWithDelegate:(id)aDelegate {
    if (nil != self) {
       
        [self.objectManager setClient:[RKClient sharedClient]];
        [[RKClient sharedClient] setUsername:[self.prefs objectForKey:kUserDefaultsCurrentUsername]];
        [[RKClient sharedClient] setPassword:[self.prefs objectForKey:kUserDefaultsCurrentPassword]];
        [[RKClient sharedClient] setServiceUnavailableAlertEnabled:YES];

        NSString *path = [NSString stringWithFormat:@"/attributes/things?login_id=%@&password=%@",
                          [self.prefs objectForKey:kUserDefaultsCurrentUsername], [self.prefs objectForKey:kUserDefaultsCurrentPassword]];
       
       
        self.loader = [self.objectManager loaderWithResourcePath:path];
        loader.delegate= aDelegate;
        loader.userData = kUserDefaultsRooms;
        loader.method = RKRequestMethodGET;
       
       
        [loader send];

Hello? Is this thing on?

Again RKObjectMapperDelegate is adoptable, but the only ObjectMapper to delegate for is pretty deep within the RK code. Anyone have a solution?
