Hi Minko, I am still not sure if we are talking about the same stuff. A routable line is one that has roadspeed/class and a non-extended type. These lines are internally called roads. The algo in StyledConverter collects all lines (routable and not-routable) in different lists, and after removal of wrong angles and obsolete points, all non-routable lines are added before all roads. The order within the two different lists is maintained. So, the order is only important if you add multiple non-routable lines or multiple roads for one OSM way . Felix said he adds up to 7 lines for one OSM way, so we should find out which combinations are bad. Gerd

Hi Gerd
just to make sure: your style creates two lines for one OSM way, they have different types, but both below 0x3f,
Well, it doesnt happen if 0x02 is replaced by 0x31. I think it only happens with "standard" routable line types (0x01-0x13, 0x16, 0x1a,0x1b) but i havent tested them all
and one has road speed/class , the other has not. Which one come first?
The ones with routing parameters come first. After this I handle the cycle routes with line 0x02 to make sure they are always rendered on top (on all GPS devices). I always needed to put on 0x02 routing parameters too because of this issue. I thought I might give it a try to remove them, but it seems the issue is still the case.
I think when it causes problems, we should try to find a better solution or print a warning.
A warning would be fine, in case multiple routable lines are detected. If that's too complicated, I would suggest to print the old warning only with --check-styles: "Non-routable way with routable type 0x.. starting at ... is used for a routable map. This can lead to routing errors if multiple routable lines on this way are used."
