[mkgmap-dev] NullPointerException & housenumber rules

Mon Apr 8 19:25:43 BST 2013

Hi Minko,

great test!
The problem was caused by the "delete addr:housenumber" action.
The housenumber generator collects the nodes and ways containing the 
housenumber information *before* the style file is processed. But the 
housenumber itself is parsed *after* the style file is processed. So it 
kept the nodes with addr:housenumber which was removed by your style 
file and therefore the parser failed.

This case is now catched and you have given me a good hint that I have 
to improve the housenumber generator to work with the style file house 
number assignments.

Thanks!
WanMil
