RestKit 2nd-level object mapping

Question

I'll try to explain how I want the mapping done:

TOP lvl json object contains Players object which is an array of Player objects each Player object contains an array, I want each of those objects in the array to be of an Event object (custom object).

now since I have a mapping of the Player object and i'm getting the array filled, tho instead of Event objects(which is what I want), i'm getting NSDictionary objects. thing is that I do have a mapping of my Event class. my issue is getting the RestKit to map these into the array. I've tried adding responseDescriptors of an Event class tho i've had no luck.

Here is the Player object mapping

 RKObjectMapping* playerMapping = [RKObjectMapping mappingForClass:[Player class]];
    [playerMapping addAttributeMappingsFromDictionary:@{
                                        ...more here              
                                           @"activeEvents" : @"activeEvents"
                                                         }];

here is the request method

 NSURL *taskURL = [NSURL URLWithString:kAppWebApiURLPath];

    // Set object manager with base url
    RKObjectManager *objectManager = [RKObjectManager sharedManager];
    objectManager = [RKObjectManager managerWithBaseURL:taskURL];
    objectManager.requestSerializationMIMEType = RKMIMETypeJSON;

    [objectManager.HTTPClient setDefaultHeader:@"Authorization" value:kAppWebAPIKey];
    [objectManager.HTTPClient setDefaultHeader:@"Content-Type" value:@"application/json"];

RKRequestDescriptor * requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:[MappingProvider inverseLoginMapping]  objectClass:[LoginInfo class] rootKeyPath:nil method:RKRequestMethodPOST];

[objectManager addRequestDescriptor:requestDescriptor];

RKResponseDescriptor *playersResponseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:[MappingProvider playerMapping] method:RKRequestMethodGET pathPattern:nil keyPath:@"players" statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

[objectManager addResponseDescriptor:playersResponseDescriptor];

NSLog(@"%@",loginInfo.iOSDeviceToken);
[objectManager postObject:loginInfo path:kAppWebApiLoginPath parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult)
 {}...

Update, I now need one step further of mapping, My player object contains an array of events which I successfully mapped using

[playerMapping addRelationshipMappingWithSourceKeyPath:@"activeEvents" mapping:[MappingProvider eventMapping]];

yet now each of those Event objects contains an array of Players, so its like Players -> Events -> Players.

Here is the Mapping for both Event and Player objects :

RKObjectMapping* eventMapping = [RKObjectMapping mappingForClass:[Event class]];

    [eventMapping addAttributeMappingsFromDictionary:@{

              @"stuffhere" : @"stuffz"                              
                                                       }];


    RKObjectMapping* playerMapping = [RKObjectMapping mappingForClass:[Player class]];
    [playerMapping addAttributeMappingsFromDictionary:@{
                                                        @"name": @"name",
                                                        @"activeEvents" : @"activeEvents"
                                                        }];
    [eventMapping addRelationshipMappingWithSourceKeyPath:@"activeEvents/players" mapping:playerMapping];

now I don't get a recursive function, but how do I state in code to make that relationship mapping of the json array to assign to my local array property ?

Remove @"activeEvents" : @"activeEvents" from the mapping and replace it with:

[playerMapping addRelationshipMappingWithSourceKeyPath:@"activeEvents" mapping:eventMapping];

You should also only have one response descriptor because the data is nested.
