legend not getting created

PeteVitt — Mon, 02 Dec 2013 14:39:43 GMT

Hi - I've pretty much copied the legend dijit sample into my app and the legend isnt getting created. When I debug it appears that the map.on layers-add-result event isnt getting fired.

here's the code:

 //create the map         map = new Map("mapDiv", {             basemap: "topo",             //center: [-117.4408, 33.8419],             center: [-117.4408, 33.4419],             zoom: 9         });                    dynamicLayer = new ArcGISDynamicMapServiceLayer("http://www.sawpa.net/arcgissawpa/rest/services/CEDEN_TMDL/MapServer", {     });     map.addLayer(dynamicLayer);     featureLayer = new FeatureLayer("http://www.sawpa.net/arcgissawpa/rest/services/CEDEN_TMDL/MapServer/0", {     });  //add legend map.on("layers-add-result", function (evt) {     var layerInfo = arrayUtils.map(evt.layers, function (layer, index) {         return { layer: layer.layer, title: layer.layer.name };     });     if (layerInfo.length > 0) {         var legendDijit = new Legend({             map: map,             layerInfos: layerInfo         }, "LegendDiv");         legendDijit.startup();     } });

I've got a LegendDiv inside a Title Pane also:

<div style="position: absolute; right: 20px; top: 50px; z-index: 999;">
            <div data-dojo-type="dijit/TitlePane" data-dojo-props="title:'Legend', closable:false, open:false">
                <div data-dojo-type="dijit/layout/ContentPane" style="width: 380px; height: 280px;
                    overflow: auto;">
                    <div id="LegendDiv">
                    </div>
                </div>
            </div>
   </div>

Any ideas?

Thanks

Pete

If you're using "map.addLayer", the event "layer-add-result" is fired.

When you use "map.addLayers", the event "layers-add-result" is fired

I made that change, but the event is still not firing

Thanks

Can you post your revised code?

This works for me

Thanks Ken - using your sample I got it to work -- I was using map.addLayer instead of map.AddLayers
