[OpenLayers-Users] Problem Geoserver Layer

[Gery .]

Hola Luis,

I work with mapserver instead of geoserver, so not sure if yz can be the problem. I think you have to test first getting the map without layers, since you're working only with 900913, just plot the OSM baselayer first in OL, if that works then put things above, ie. your geoserver layers.

Salu2,

Gery

    Hi everyone,

    

    I'm new with openlayers, and i'm trying to create a new map with one
    layer served with Geoserver, but i'm getting some problems.

    

    This is the code:

    

    "//Definimos la variable map

        var map;

        function init() {

              //Opciones

              var options = {

                                    projection: new
        OpenLayers.Projection("EPGS:900913"),

                                    units: "m"                          
        

                                 

                                 };

             

              //Creamos un nuevo objeto map en el div con el id = map

              map = new OpenLayers.Map('map',options);

              

                 var mapnik = new OpenLayers.Layer.OSM();

        

                

                

                //Añadir capa Geoserver Pruebas

                var prueba =  new OpenLayers.Layer.WMS(

                            "Test:comarca - Tiled",
        "http://localhost:8080/geoserver/Test/wms",

                            {

                                LAYERS: 'Test:comarca',

                                format: 'img/png'

                            },

                            {                

                                isBaseLayer: false,

                                yx : {'EPSG:900913' : false}

                            } 

                        );

                 

                

              // Añadir la capa al mapa

                map.addLayer(mapnik);

                

                map.addLayer(prueba);

                

                

                //Poner el centro del mapa en estas coordenadas.

                map.setCenter(new
        OpenLayers.LonLat(-412267.21675,4926706.34959),6);

                

                

                

                //Controles

                map.addControl(new
        OpenLayers.Control.LayerSwitcher());        

                map.addControl (new OpenLayers.Control.MousePosition 
        ());

                map.addControl(  new OpenLayers.Control.ScaleLine());

               }"

    

    But Firebug show me this error: 

    

    TypeError: a is null

        http://localhost/arqueoserver3/OpenLayers-2.12/OpenLayers.js

        Line 467

    

    What I'm doing wrong? Probably is something stupid, but i can't see
    it. 

    

    Thanks.
