Hi,
I’m trying to update some rules in my theme file to control which type of huts and shelters to show.
I have a question about this item, which has amenity=shelter and shelter_type=basic_hut.
Of course, it shows with any of these rules:
<rule e="any" k="amenity" v="shelter">
<rule e="any" k="shelter_type" v="basic_hut">
but also with:
<rule e="any" k="amenity" v="basic_hut">
Why is that? I can’t find an reason looking at tagmapping or in tagtransform.
Thanks!

It’s what’s known as the common value bug. Basically the Mapsforge renderer collects the data values of the item together in a list like:
k=amenity, shelter_type
v=shelter, basic_hut
Then k matches on any of the values in the k list, and v matches on any of the values in the v list.
The same thing happens with all variables so you have to build your tests with this in mind.
