Hi Guys,

thanks for testing my stuff.

Yes this is indeed a bug. I should just ignore the postcode if there is 
a list.

I also don't like the auto filling that much. Problem is that with the 
current osm data most location will end up in the default country / 
region since is_in tagging is rare for hamlets in Germany. This will 
make it difficult to distinguish between hamlets with same name in the 
city list. And in most other countries situation is even worse. I don't 
have a problem to disable the heuristic by default as long as there is a 
switch to enable it ...

What should we do with the Road POI's ? I think disabling heuristic for 
them makes no sense since we need the city name to make them more unique.

I experimented a little bit with ZIP data provided by geonames.org. This 
seams to help to improve the quality of the heuristic in non opengeodb 
countries. But this datasource also provides points and no polygons so 
it will be still guessing. I also looked a little bit in using 
administrative boundary data for the region naming but I'm not sure if 
the data sources are good enough ...

I hope I could provide a patch with your suggestions on the weekend ...

Thanks
Berni.
