Hi Team,
We are developing an application using offline store in native iOS. While trying to do a deep insert with 1-1 relation using offline store, it is posting twice to the backend while flushing. But the entry is created only once in the offlinestore.
The code which I used is :
SODataEntityDefault *parentEntity = [[SODataEntityDefault alloc] initWithType:@"MerchReview"]; [parentEntity setResourcePath:@"MerchReviews" editResourcePath:@"MerchReviews"]; [[DataController shared].offlineStore allocatePropertiesOfEntity:parentEntity mode:SODataRequestModeCreate error:&anError]; SODataPropertyDefault* reviewKey = [[SODataPropertyDefault alloc] initWithName:@"MerchReviewKey"]; [reviewKey setValue:string_id]; [[parentEntity properties] setObject:reviewKey forKey:reviewKey.name]; SODataPropertyDefault* visitKey = [[SODataPropertyDefault alloc] initWithName:@"VisitKey"]; [visitKey setValue:@""]; [[parentEntity properties] setObject:visitKey forKey:visitKey.name]; SODataPropertyDefault* customerName = [[SODataPropertyDefault alloc] initWithName:@"CustomerNo"]; [customerName setValue:[[NSUserDefaults standardUserDefaults] objectForKey:@"SELECTEDDEALERNO"]]; [[parentEntity properties] setObject:customerName forKey:customerName.name]; SODataPropertyDefault* loginID = [[SODataPropertyDefault alloc] initWithName:@"LoginID"]; [loginID setValue:[[NSUserDefaults standardUserDefaults] objectForKey:@"USERNAME"]]; [[parentEntity properties] setObject:loginID forKey:loginID.name]; SODataPropertyDefault* reviewDate = [[SODataPropertyDefault alloc] initWithName:@"ReviewDate"]; [reviewDate setValue:paymentDate]; [[parentEntity properties] setObject:reviewDate forKey:reviewDate.name]; SODataPropertyDefault* reviewType = [[SODataPropertyDefault alloc] initWithName:@"ReviewType"]; [reviewType setValue:@"01"]; [[parentEntity properties] setObject:reviewType forKey:reviewType.name]; SODataPropertyDefault* reviewLatitude = [[SODataPropertyDefault alloc] initWithName:@"ReviewLatitude"]; [reviewLatitude setValue:latitudeValue]; [[parentEntity properties] setObject:reviewLatitude forKey:reviewLatitude.name]; SODataPropertyDefault* reviewLongitude = [[SODataPropertyDefault alloc] initWithName:@"ReviewLongitude"]; [reviewLongitude setValue:longitudeValue]; [[parentEntity properties] setObject:reviewLongitude forKey:reviewLongitude.name]; SODataPropertyDefault* remarks = [[SODataPropertyDefault alloc] initWithName:@"Remarks"]; [remarks setValue:[txtField_Remarks.text length]>0?txtField_Remarks.text:@""]; [[parentEntity properties] setObject:remarks forKey:remarks.name]; /**********/ SODataEntityDefault *entityForCreation = [[SODataEntityDefault alloc] initWithType:@"SFGW.MerchReviewImage"]; [entityForCreation setResourcePath:@"MerchReviewImages" editResourcePath:@"MerchReviewImages"]; [[DataController shared].offlineStore allocatePropertiesOfEntity:entityForCreation mode:SODataRequestModeCreate error:&anError]; SODataPropertyDefault* propVisitKey = [[SODataPropertyDefault alloc] initWithName:@"MerchRevImageKey"]; [propVisitKey setValue:string_id]; [[entityForCreation properties] setObject:propVisitKey forKey:propVisitKey.name]; SODataPropertyDefault* propRoutePlanKey = [[SODataPropertyDefault alloc] initWithName:@"MerchReviewKey"]; [propRoutePlanKey setValue:string_id]; [[entityForCreation properties] setObject:propRoutePlanKey forKey:propRoutePlanKey.name]; SODataPropertyDefault* propLoginID = [[SODataPropertyDefault alloc] initWithName:@"MimeType"]; [propLoginID setValue:@"JPEG"]; [[entityForCreation properties] setObject:propLoginID forKey:propLoginID.name]; SODataPropertyDefault* propDate = [[SODataPropertyDefault alloc] initWithName:@"Size"]; [propDate setValue:[NSString stringWithFormat:@"%d", imageSize]]; [[entityForCreation properties] setObject:propDate forKey:propDate.name]; SODataPropertyDefault* propVisitType = [[SODataPropertyDefault alloc] initWithName:@"Image"]; [propVisitType setValue:imageString]; [[entityForCreation properties] setObject:propVisitType forKey:propVisitType.name]; NSError *error = nil; [[DataController shared].offlineStore allocateNavigationProperties:parentEntity error:&error]; NSString* const resourcePath = [NSString stringWithFormat:@"MerchReview(%d)", [string_id intValue]]; [parentEntity setResourcePath:resourcePath editResourcePath:resourcePath]; NSObject* navigationProperty = [(id<SODataEntity>)parentEntity navigationPropertyForRelationIdentifier:@"MerchReviewImages"]; id<SODataNavigationProperty> imageNavigationProperty = (id<SODataNavigationProperty>)navigationProperty; [imageNavigationProperty setNavigationContent:entityForCreation]; [parentEntity setNavigationProperty:imageNavigationProperty forRelationIdentifier:@"MerchReviewImages"]; NSString *finishedSubscription = [NSString stringWithFormat:@"com.sap.sdk.request.delegate.finished"]; // send notification for the finished request [[NSNotificationCenter defaultCenter] addObserverForName:finishedSubscription object:nil queue:[NSOperationQueue mainQueue] usingBlock:^(NSNotification *note) { if(networkStatus == 2) { UIAlertView *alt_view = [[UIAlertView alloc] initWithTitle:@"mSFA" message:@"We are unable to make a internet connection at this time. Some functionality will be limited until a connection is made." delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alt_view show]; [self hide_indicator]; } else { [self show_indicator]; dispatch_async(dispatch_get_global_queue(0, 0), ^{ [[DataController shared].offlineStore scheduleFlushQueuedRequestsWithDelegate:[DataController shared]]; dispatch_async(dispatch_get_main_queue(), ^{ [self hide_indicator]; }); }); } UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"mSFA" message:@"Review created successfully" delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil]; [alert show]; }]; [[DataController shared].offlineStore scheduleCreateEntity:parentEntity collectionPath:@"MerchReviews" delegate:[DataController shared] options:nil];Same behaviour is noticed in Android also.
SDK Version is SP11.
