[Users] problem using 'legendURL'

[Bart van den Eijnden (OSGIS)]

Hmm, strangely enough it is not in the API docs [1], however in
GeoExt/data/LayerStore.js:

        /** public: method[getByLayer]
         *  :param layer: ``OpenLayers.Layer``
         *  :return: :class:`GeoExt.data.LayerRecord` or undefined if not
found
         *
         *  Get the record for the specified layer
         */
        getByLayer: function(layer) {
            var index = this.findBy(function(r) {
                return r.get("layer") === layer;
            });
            if(index > -1) {
                return this.getAt(index);
            }
        },

Bart
