title: CoreData mapping with JSON array with RestKit 0.20?
body: <p>I have a <code>JSON</code> as follows</p>
  
  <pre><code>{
      "code":0,
      "response":{
          "Cirqit":{
              "Cirqit":{...},
              "Owner":{...},
              "CirqitMembers":[
                  {
                      "User":{...},
                      "CirqitMember":{...}
                  },
                  {
                      "User":{...},
                      "CirqitMember":{...}
                  }
              ]
          }
      }
  }
  </code></pre>
  
  <p>My mapping Code is below:</p>
  
  <pre><code>   //User mapping
      RKEntityMapping *userMapping = [RKEntityMapping mappingForEntityForName:@"User" inManagedObjectStore:apiInterface.managedObjectStore];
      NSDictionary *userMappingDict = @{@"id": @"id",@"firstname": @"firstname"};
      [userMapping addAttributeMappingsFromDictionary:userMappingDict];
  
      //Member Status Mapping
      RKEntityMapping *membStatusMapping = [RKEntityMapping mappingForEntityForName:@"MemberStatusInfo" inManagedObjectStore:apiInterface.managedObjectStore];
      NSDictionary *membStatusMappingDict = @{@"id": @"id",@"user_id": @"user_id"};    [membStatusMapping addAttributeMappingsFromDictionary:membStatusMappingDict];
  
      //Cirqit Member Mapping
      RKEntityMapping *membMapping = [RKEntityMapping mappingForEntityForName:@"CirqitMember" inManagedObjectStore:apiInterface.managedObjectStore];
      NSDictionary *membMappingDict = @{ @"CirqitMember.id":@"id" };
      [membMapping addAttributeMappingsFromDictionary:membMappingDict];
      [membMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"response.Cirqit.CirqitMembers.User" toKeyPath:@"memberStatus" withMapping:userMapping]];
      [membMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"response.Cirqit.CirqitMembers.CirqitMember" toKeyPath:@"memberDetails" withMapping:membStatusMapping]];
      membMapping.identificationAttributes = @[@"id"];
  
      //Cirqit Mapping
      RKEntityMapping *cirqitMapping = [RKEntityMapping mappingForEntityForName:@"Cirqit" inManagedObjectStore:apiInterface.managedObjectStore];
      NSDictionary *cirqitMappingDict = @{   @"response.Cirqit.Cirqit.id":@"id",
                                   @"response.Cirqit.Cirqit.allow_invite": @"allow_invite"};    
      [cirqitMapping addAttributeMappingsFromDictionary:cirqitMappingDict];
      [cirqitMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"response.Cirqit.CirqitMembers" toKeyPath:@"cirqitMembers" withMapping:membMapping]];
      cirqitMapping.identificationAttributes = @[@"id"];
  
      NSIndexSet *statusCodes = RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful);
      RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:cirqitMapping pathPattern:nil keyPath:nil statusCodes:statusCodes];
      operation = [apiInterface getOperationWithRequest:request forResponseDescriptors:@[responseDescriptor]];
      [operation start];
  </code></pre>
  
  <p>Here membMapping,cirqitMapping works fine. but membStatusMapping,userMapping is not working. Actually there is no mapping error but mapping is not occured.</p>
  
  <p>My Managed object class below:</p>
  
  <pre><code>@interface CirqitMember : NSManagedObject
  
  @property (nonatomic, retain) NSNumber * id;
  @property (nonatomic, retain) MemberStatusInfo *memberDetails;
  @property (nonatomic, retain) User *memberStatus;
  
  @end
  </code></pre>
