Several years ago we created JOSM paint styles to help with the task of mapping gritting routes. The styles made it easier to identify which roads had the gritting tag.
The recent versions of JOSM have changed the requirements of these style plugins therefore breaking our code. If you still use the style you will see the following message that gives the reasoning and how to fix the problem. The style plugin would need to be updated to the latest MapCCS code.
This applies to both our josm-style.xml and josm-preset.xml code. Currently we have no plans to update these style plugins to the latest MapCCS code, however we welcome support from others to complete this update. If someone can come forward we will upload the new code so the functionality continues to work. For now, to prevent the warning message popping up each time you start JOSM, simply go to “View -> Map paint styles -> Map paint preferences” and delete “Winter Gritting” and “Winter Gritting2”.
We apologise for any inconvenience this causes.
