[OpenLayers-Users] Layer rendering

[Carlos Pinto]

Hi all,

Thanks very much. It is working and now I can start doing my grids.

the code is:

            var styleMap = new OpenLayers.StyleMap({
                fillOpacity: 1});

        var lookup = {
           0: {fillColor: "green", fillOpacity: 1, strokeColor: "green"},
           1: {fillColor: "red", fillOpacity: 0.5, strokeColor: "red"}
        }
        styleMap.addUniqueValueRules("default", "type", lookup);

        var mylayer =   new OpenLayers.Layer.GML("GML",
"../KML/MyPolygons.xml",{styleMap: styleMap} );
        map.addLayer(mylayer);
        }


but one thing funny is that if I use the line

myLayer.styleMap = styleMap;

it does not work


Thanks all especially to Andreas.
