JOSM does not query API for referring relations when downloading primitives

[Nakor]

Download data using the following bounding box: ​http://www.openstreetmap.org/?lat=42.65924&lon=-83.3199&zoom=17

Download all members from the relation

Search for way 43418202. It is shown only as a member of relation 308,352 but if it is also member of another relation (see ​http://www.openstreetmap.org/browse/way/43418202).

This would cause inconsistencies if the way is split.

When downloading primitives from the API (with multi get) the API does not return relations the primitive is member of. There is a special API call for that:

GET /api/0.6/[node|way|relation]/#id/relations

(see ​http://wiki.openstreetmap.org/wiki/API_v0.6#Relations_for_Element:_GET_.2Fapi.2F0.6.2F.5Bnode.7Cway.7Crelation.5D.2F.23id.2Frelations)

JOSM needs to iterate over all downloaded primitives and check whether they are members of any relation.

Better would be if the API provided a call like

GET /api/0.6/[nodes|ways|relations]/#ids/complete

that returns the same kind of data like the map call.

Any update on this critically prioritized ticket?

Maybe a warning with an option to download parents before splitting could help as these ways are outside of the download area.
