Trying to create a mapframe with Glomma fails to render. Mapframe is defined as
<mapframe text="Geoline av Glomma" width=300 height=300 zoom=6 latitude=61.24 longitude=9.20> { "type": "ExternalData", "service": "geoline", "properties": {"title": "Glomma"}, "ids": "Q214535" } </mapframe>
The item at OSM is this one.
This example is used at w:no:Wikipedia:Torget#Dårlig med kart på wikipedia. It is the second example.
Note that the lat-lon is not accurate, it is reused from the map for "Oppland", which is shown in the same thread at Wikipedia:Torget.
