I have a GeoExt.LegendPanel which is working just fine for layers which are not grouped. However, the grouped layers do not show any icon in the LegendPanel. I have tried to create the group layer various ways, using the exact name of the layer group in Geoserver and aldo by specifying a layer string in code. I've been looking around for a while now, but I don't see what I am missing..

Here is relevant code:

//Layer Group
var geography2 = new OpenLayers.Layer.WMS(
                    "Geography2", "http://localhost:8080/geoserver/wms", {layers: 'cite:geog_multipol_vw,cite:geog_multiline_vw', transparent: true}, {isBaseLayer: false, displayInLayerSwitcher: true, visibility: true, minScale: 27734017.045258757}

//LegendPanel config
var legend = new GeoExt.LegendPanel({
                region: "east",
                title: "Legend",
                width: 200,
                autoScroll: true,
                layerStore: mapPanel.layers

//Explicitly point LegendPanel to GetLegendGraphic on WMS Geoserver for GeoWebCached Layers
            var LayerRec;
            for(var l = 4; l < map.layers.length; l++)
                LayerRec = mapPanel.layers.getAt(l);
                LayerRec.set("legendURL","http://localhost:8080/geoserver/wms?TRANSPARENT=true&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetLegendGraphic&EXCEPTIONS=application%2Fvnd.ogc.se_xml&FORMAT=image%2Fgif&LAYER=" + map.layers[l].params["LAYERS"]);

Thanks for your time in trying to help me :),


You post this questions a while ago. Did you find a solution for your problem? I found your post because I'm looking for a solution to a similar problem. Anyway, in your code, you start at checking the layers from index 4. I was wondering if it was I typo, or something related to the part of the code that we don't see. –  user2860 May 3 '11 at 4:06

do the legend graphics work when you request them directly in the browser? If so there is a problem with the way you are adding them to the legend panel, if not then there is a problem with GeoServer and you need to file a bug report.
