[Users] Do not work me the DescribeFeatureType query to create a Attribute Store

[jcortega at dipalme.org]

Hi all,

I'm following the tutorial “Developing OGC Compliant Web Applications with 
Geoext” and I have some problem with the second lesson 3.1 “ Creating a 
Synchronized Grid and Map View of WFS Features” 
http://workshops.opengeo.org/geoext/wfs/grid.html.

I'm trying to create a gridpanel in Geoext, that must be filled with the 
names of the fields from an AttributeStore and then create their own 
FeatureStore with the values of these fields and update the grid panel.

The problem is that when I select a layer and execute the funcion setLayer 
that create the attribute sotore (schema),   no execute never the listener 
load and therefore I can not get the name of fields

My code is as follows:


function setLayer(model, node) {
 
                if(!(node && node.layer instanceof OpenLayers.Layer.WMS)) 
{
                        return;
                }
                selectedLayer = null;
                vectorLayer.removeAllFeatures();
                app.featureGrid.reconfigure( new Ext.data.Store(),new 
Ext.grid.ColumnModel([]) );
        var layer = node.layer;
                var url = layer.url.split("?")[0];
                alert("capa seleccionada: " + layer.params.LAYERS);
                schema = new GeoExt.data.AttributeStore({
 
                                        url: url,
                                                baseParams: {
 "SERVICE": "WFS",
 "REQUEST": "DescribeFeatureType",
 "VERSION": "1.1.0",
 "TYPENAME": layer.params.LAYERS
                                                },
 
                                         autoLoad: true,
                                         listeners: {
                                                                load : 
function(store, records, index) {
  alert ("load");
        app.featureGrid.setTitle(layer.name);
        selectedLayer = layer;
        configureGrid(store, url);
                           }
                                                           }  //listeners
 
                });         // final de schema
    }
