Gents, With newest release r3693 I'm having troubles creating a map with a style file 'line' containing the following expression (it worked with r3649 and earlier version): maxspeed = * & ( maxspeedkmh()>120 | maxspeed = none ) & ( highway = motorway | highway = trunk ) { set mkgmap:road-speed-class = 7 } It bailes out with the following error codes in the output: java -Xmx1536M -jar D:/fzk/develop/fzk-mde-garmin/Freizeitkarte-Entwicklung/tools/mkgmap/mkgmap.jar --max-jobs=2 -c Freizeitkarte_CHE.cfg --check-styles Time started: Fri Aug 12 12:14:08 CEST 2016 Found one style in D:/fzk/develop/fzk-mde-garmin/Freizeitkarte-Entwicklung/work/Freizeitkarte_CHE_de/style/fzk Error in style: Error: (lines:442): Invalid rule expression: (((maxspeedkmh()>120)|($maxspeed='none'))&((($highway='motorway')|($highway='trunk'))&$maxspeed=*)) could not open style fzk finished check-styles Error in style: Error: (lines:442): Invalid rule expression: (((maxspeedkmh()>120)|($maxspeed='none'))&((($highway='motorway')|($highway='trunk'))&$maxspeed=*)) Error in style: Error: (lines:442): Invalid rule expression: (((maxspeedkmh()>120)|($maxspeed='none'))&((($highway='motorway')|($highway='trunk'))&$maxspeed=*)) Error in style: Error: (lines:442): Invalid rule expression: (((maxspeedkmh()>120)|($maxspeed='none'))&((($highway='motorway')|($highway='trunk'))&$maxspeed=*)) Error in style: Error: (lines:442): Invalid rule expression: (((maxspeedkmh()>120)|($maxspeed='none'))&((($highway='motorway')|($highway='trunk'))&$maxspeed=*)) Could not open style Number of ExitExceptions: 1 When just changing the order of the expressions (without changing the logic/result) as shown below it works properly also with release r3693: maxspeed = * & ( highway = motorway | highway = trunk ) & ( maxspeedkmh()>120 | maxspeed = none ) { set mkgmap:road-speed-class = 7 } Is it possible that the 'fixes' for r3667 or r3671 fixed some errors but brought a new one in ? Or do I completely misunderstand the concept of these expressions ? Thanks for checking Patrik
