I am successfully applying the following StyleMap to a vector layer:
var vectorStyles = new OpenLayers.StyleMap({
'default' : new OpenLayers.Style({
fillColor: "#FF0000"
,fillOpacity: 0.1
,pointRadius: 4
,strokeColor: "#FF0000"
,strokeWidth: 2
})
,'select': new OpenLayers.Style({
fillColor: "#0000FF"
,fillOpacity: 0.4
,strokeColor: "#0000FF"
})
,'temporary': new OpenLayers.Style({
fillColor: "#FF0000"
,fillOpacity: 0.1
,strokeColor: "#FF0000"
,strokeWidth: 2
,strokeDashstyle: 'dot'
,pointRadius: 4
,cursor: 'crosshair'
})
});
However, I wish to change the "default" fillColor and strokeColor based on a
feature attribute, called Colour, as follows:
'default' : new OpenLayers.Style({
fillColor: "${Colour}"
,fillOpacity: 0.1
,pointRadius: 4
,strokeColor: "${Colour}"
,strokeWidth: 2
})
However, when using attribute replacement, the fill and stroke style
properties of the polygon handles are set to "undefined" in modify mode. I
have attempted to set the extendDefault to false in the StyleMap, and
explicitly set the colours in the "select" intent, but to no avail.
