Hi Karsten,
WMSLegend does not listen to LegendURL, only UrlLegend does.
Feel free to open up a github ticket, and patches welcome as always (should be
an easy patch). Something like (not tested):
getLegendUrl: function(layerName, layerNames) {
var rec = this.layerRecord;
if (rec.get("legendURL") != null) {
return rec.get("legendURL");
} else {
… continue as we do now
Best regards,
Bart
