[Users] adding legendURL, legend tree

[Bart van den Eijnden]

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
