[mkgmap-dev] NullPointerException & housenumber rules

Mon Apr 8 13:25:55 BST 2013

Hi,

I've got a NullPointerException error when I add the following line to the address rules (inc/address file)

addr:housenumber=* & addr:street=* & source=BAG {delete addr:housenumber}

I put this line before the following lines:

mkgmap:street!=* & addr:street=* { set mkgmap:street='${addr:street}' }
mkgmap:street!=* & addr:housename=* { set mkgmap:street='${addr:housename}' }

This rule I want to add because I merge so called BAG dataset later to my osm extract,
and I want to filter all BAG data that has already been imported in the NL's until now.

If you put the line at the end of the address file everything is ok (but probably doesn't do anything).
It happens with the default style as well as my own styles.

The NPE occurs with mkgmap-r2544, r2560 and mkgmap-overview2 jar files with --x-housenumbers
With mkgmap-r2538 this NPE does not occur.

One of the tiles that is affected and contains the tag addr:housenumber=* & addr:street=* & source=BAG as well as my merged BAG data is uploaded here:

The error message is
