11436	[MapCSS] Failure on complicated eval commands	Aun Johnsen <lists@…>	team	"In a github issue ([https://github.com/OpenSeaMap/josm]/[https://github.com/OpenSeaMap/josm/issues/19 issue#19]) I was made aware of white square icons where multicoloured seamark icons should have been visible. I tested the area mentioned in my own copy of JOSM, also seeing the same white square placeholders. I than moved to the test area I used when last editing the MapCSS file, and to my disappointment encountered same problem there.

I know for a fact this worked in stable release of March, I always use stable when testing and correcting stylesheets, and offsetting of these icons was edited and committed on March 14, I did not check whether this worked in April, but since I didn't notice anything wrong believe so, I didn't edit seamarks, but very often have this style active also when editing other features.

Have this been caused with latest changes in MapCSS implementation, or have there been a planned syntax change?

Code block in question, see ([https://github.com/OpenSeaMap/josm/blob/master/INT1_MapCSS.mapcss#L503 here])

}

}}}

Example object in first area should have given the following URL:

https://raw.githubusercontent.com/OpenSeaMap/josm/master/icons/svg/Q/can/horizontal/red_white_red_white.svg

instead of 

https://raw.githubusercontent.com/OpenSeaMap/josm/master/icons/svg/Q//.svg

==== What steps will reproduce the problem?
1. Add paint style in https://github.com/OpenSeaMap/josm/raw/master/INT1_MapCSS.mapcss
2. Load area in  https://www.openstreetmap.org/#map=13/52.5844/5.8419 or https://www.openstreetmap.org/#map=13/-22.8559/-43.153

==== What is the expected result?
You are expected to see several icons rendered as nautical symbols in accordance with IHO INT-1 standard

==== What happens instead?
White placeholder icons shown instead of the expected symbols

==== Please provide any additional information below. Attach a screenshot if possible.
