Hi,I am using the 10.2.2 version of the SDK and working with the offline editing capabilities. The particular layer I am working with has a GUID type field in addition to the GlobalID field. When I try to save a new AGSGDBFeature to the AGSGDBFeatureTable the app crashes. I have been able to successfully save to that layer without supplying a value for the GUID field. SQLite does not have a GUID datatype. When Server for ArcGIS generates the geodatabase it represents GUID field types as uuidtext custom type in SQLite. The name suggests that this is a text type field. If I open the geodatabase in SQLite Manager (Firefox add-in) I can successfully paste a GUID string into the edit dialog for a row and save. This tells me that it is not a SQLite error. I'm wondering if anyone else has tried this yet and if this may be a bug in the SDK. AGSGDBFeatureTable* fbFeatTable = [self.geodatabase featureTableForLayerID:1]; if (fbFeatTable.canCreate && fbFeatTable.canUpdate) { AGSGDBFeature* feature = [[AGSGDBFeature alloc] initWithTable:fbFeatTable]; // I've tried these variations //[feature setAttribute:[NSUUID UUID] forKey:@RecGuid]; //[feature setAttribute:[[NSUUID UUID] UUIDString] forKey:@RecGuid]; //[feature setAttribute:[NSString stringWithFormat:@{%@}", [[NSUUID UUID] UUIDString]] forKey:@RecGuid]; [feature setAttributeWithString:[NSString stringWithFormat:@{%@}", [[NSUUID UUID] UUIDString]] forKey:@RecGuid]; [feature setAttributeWithString:@Test1 forKey:@aaa]; [feature setGeometry:geometry]; NSError* saveError; if ([fbFeatTable saveFeature:feature error:&saveError]) { NSLog(@Saved.); } else { NSLog(@Error Saving: %@", saveError); } } else { NSLog(@%@ does not allow new features.", fbFeatTable.tableName); }Thanks,Justin
