22539	Error in MAPCSS regarding LAYER and SET's ?	mikeho	team	"I am in the process of building some useful mapcss for JOSM. Concerning the turnouts this works, in that I have stored a corresponding graphic for each configuration.

Regarding the signals I had the idea to build the possible signal states on the fly from a few graphics (e.g. black background in front of green / red / yellow dot for ks1 / hp0 / ...).

The following works:
{{{#!mapcss
node z17-[""railway:signal:combined:states"" *= ""DE-ESO:hp0""]::layer_signal_611,
node z17-[""railway:signal:main:states"" *= ""DE-ESO:hp0""]::layer_signal_611 {
    z-index: 611;
    icon-image: ""icons/light_rr.png"";
    icon-offset-x: 0;
    icon-offset-y: -20;
    allow-overlap: true;
}
node z17-[""railway:signal:combined:states"" *= ""DE-ESO:ks1""]::layer_signal_612,
node z17-[""railway:signal:main:states"" *= ""DE-ESO:ks1""]::layer_signal_612 {
    z-index: 612;
    icon-image: ""icons/light_gr.png"";
    icon-offset-x: -5;
    icon-offset-y: -10;
    allow-overlap: true;
}
node z17-[""railway:signal:combined:states"" *= ""DE-ESO:ks2""]::layer_signal_613,
node z17-[""railway:signal:main:states"" *= ""DE-ESO:ks2""]::layer_signal_613 {
    z-index: 613;
    icon-image: ""icons/light_or.png"";
    icon-offset-x: 5;
    icon-offset-y: -10;
    allow-overlap: true;
}
}}}

My idea to first remember the states via Set (classes) does not work regarding the display in connection with the layers (without `::layer___` it works))

1) get status
{{{#!mapcss
node[""railway:signal:combined:states"" *= ""DE-ESO:hp0""], node[""railway:signal:main:states"" *= ""DE-ESO:hp0""] { set .sg_hp0; }

node[""railway:signal:combined:states"" *= ""DE-ESO:ks1""], node[""railway:signal:main:states"" *= ""DE-ESO:ks1""] { set .sg_ks1; }

node[""railway:signal:combined:states"" *= ""DE-ESO:ks2""], node[""railway:signal:main:states"" *= ""DE-ESO:ks2""] { set .sg_ks2; }
}}}
2) display
{{{#!mapcss
node.sg_hp0::layer_signal_611 {
    z-index: 611;
    icon-image: ""icons/light_rr.png"";
    icon-offset-x: 0;
    icon-offset-y: -20;
    allow-overlap: true;
}
node.sg_ks1::layer_signal_612 {
    z-index: 612;
    icon-image: ""icons/light_gr.png"";
    icon-offset-x: -5;
    icon-offset-y: -10;
    allow-overlap: true;
}
node.sg_ks2::layer_signal_613 {
    z-index: 613;
    icon-image: ""icons/light_or.png"";
    icon-offset-x: 5;
    icon-offset-y: -10;
    allow-overlap: true;
}
}}}
Unfortunately I didn't find anything useful at wiki:Help/Styles/MapCSSImplementation. Can't JOSM do the combo of layer and sets or am I thinking wrong?

Many greetings
