Warning on speed camera relation

[anonymous]

when mapping a speed camera I get this warning upon upload:

key "maxspeed" without street, railway or traffic sign - suspicious key/value combination (translation might not be 100% word by word since I see the German text).

I tried all different things but have no clue what might be wrong.

The device has the keys
highway=speed_camera
maxspeed=70

and the relation has set the roles to, from and device as well as the keys

addr:city=cityname
addr:country=DE
enforcement=maxspeed
type=enforcment
addr:street=streetname

I tried as well to add addr:street directly to the device node. I think I did everything as written in the osm wiki. People on the OSM forum considered it a bug in JOSM. Can you check? Thanks.

In 5529/josm:

fix #8104 - don't warn for maxspeed in enforcement relation
