This bug has been around for almost a year now, and occurred under very special circumstances only: - A user wants to remove the last member of a child relation - This child relation is part of a 3-level nested relation (child/parent/grandparent) In the case of the second example mentioned, the grandparent corresponds to the National Expressways of South Korea (relation 6818098), which includes route_master relation 4424722 (parent), which in turn references relations 4424718, 4424720, and 4424721 as children. - iD deletes both child and parent relations, but for some reason didn't adjust the grandparent->parent dependency. This is being addressed in another GitHub issue. In the API request, only child and parent relations were to be deleted using the if-unused="true" flag. This flag is set by some editors like iD, Potlatch, and GoMap!! to suppress error messages for already deleted objects. IIRC it has been introduced as a convenience feature for Potlatch back in the days. - CGImap deleted the child, although it was still required by the grandparent->parent dependency. This only happened in case the API was called with if-unused="true". An updated CGImap 0.8.2 release including a fix for this issue has been deployed already. Thanks again for providing a thorough analysis of the issue. -- _______________________________________________ dev mailing list [email protected] https://lists.openstreetmap.org/listinfo/dev
