Restkit mapping one to many - ios

Question

I have mapping like this:
RKObjectMapping *pageMapping = [RKEntityMapping mappingForEntityForName:#"Page" inManagedObjectStore:[RKManagedObjectStore defaultStore]];
[pageMapping addAttributeMappingsFromArray:#[ #"rows, columns", #"header", #"size", #"backgroundColor" ]];
RKObjectMapping *objectMapping = [RKEntityMapping mappingForEntityForName:#"Object" inManagedObjectStore:[RKManagedObjectStore defaultStore]];
[objectMapping addAttributeMappingsFromArray:#[ #"content", #"crop", #"fontName", #"fontSize", #"height", #"width",
#"paddingLeft", #"paddingTop", #"paddingRight", #"paddingBottom", #"src", #"textColor", #"type", #"url", #"posX", #"posY" ]];
[objectMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:#"objects" toKeyPath:#"objects" withMapping:pageMapping]];
RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:pageMapping pathPattern:nil keyPath:#"pages" statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
[[RKObjectManager sharedManager] addResponseDescriptor:responseDescriptor];
[[RKObjectManager sharedManager] getObjectsAtPath:[magazine contentPath]
parameters:nil
success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
[self sortPageResult];
Page *page = (Page *)[self.pagesFetchedResultController objectAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0]];
NSLog(#"%d", [[page objects] count]);
//[self changeStatusToDownloaded:[magazine magazineID]];
[self.collectionView reloadData];
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
[self displayError];
NSLog(#"Product error: %#", [error localizedDescription]);
[self.collectionView reloadData];
}];
And I've got a problem with mapping. I clearly map "page" object, but I can't map "object". When I try it I get something like this:
Relationship 'objects' fault on managed object (0x1d8b57a0) <Page: 0x1d8b57a0> (entity: Page; id: 0x1d8b0740 <x-coredata://30A44191-D972-4222-88DF-539C2875F293/Page/p1> ; data: {
backgroundColor = FFFFFF;
columns = 0;
content = nil;
header = 1;
link = nil;
magazine = nil;
margin = 0;
objects = "<relationship fault: 0x1d8aea40 'objects'>";
pageID = nil;
rows = 0;
size = 1;
})
Thx for reply!

New progress
I've changed:
[objectMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:#"objects" toKeyPath:#"objects" withMapping:pageMapping]];
instead:
[pageMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:#"items" toKeyPath:#"items" withMapping:itemMapping]];
Now is mapping right, but mapping causing duplicating "object" entities. There's only one object, which is remaking again and again :/
