[Users] Search using WFS Protocol

[Graeme Gould]

Please can I have some advice as to why the following code isn't working.  When you enter a search parameter using the formpanel and click search no results are displayed in the gridpanel, but a new blank layer called results is created.  I think it maybe something to do with connecting to Geoserver.

var protocol = new OpenLayers.Protocol.WFS({
                                    url: "http://192.168.10.44:8085/geoserver/wfs",
                                    version: "1.1.0",
                                    featureType: "aha_trees",
                                    featureNS: "http://www.grandunionhousing.co.uk/guhg_data",
                                    srsName: epsg27700,
                                    geometryName: "geometry"
});
var features = new Array();
");
var selects = new GeoExt.grid.FeatureSelectionModel();
var cols = [
            {name: 'tree_ref', type: 'string'},
            {name: 'x', type: 'string'},
            {name: 'y', type: 'integer'}
];
var reader = new GeoExt.data.FeatureReader({}, cols);
var store = new GeoExt.data.FeatureStore({
                                    id: "gridStore",
                                    reader: reader,
                                    fields: cols,
                                    autoLoad: false
});

var formPanel = new GeoExt.form.FormPanel ({
            title: "Postcode Search",
            height: 100,
            width: 350,
            bodyStyle: "padding: 5px;",
            region: "north",
            protocol: protocol,
            items: [{
                        xtype: "textfield",
                        name: "tree_ref__like",
                        allowBlank: false,
                        fieldLabel: "Tree Reference",
                        minLength: 1
            }],
            listeners: {
                        actioncomplete: function(form, action) {
                                    features = action.response.features;
                                    store.loadData(features);
                                    vm=app.mapPanel.map.getLayersByName("Results");
                                    if (vm.length===0) {
                                                vecLayer = new OpenLayers.Layer.Vector("Results");
                                                app.mapPanel.map.addLayer(vecLayer);
                                                store.bind(vecLayer);
                                                selects.bind(vecLayer);
                                    }
                        }
            },
            buttons: [{
                        text: "Search",
                        handler: function() {
                                    var mygrid = Ext.getCmp('gridPanel');
                                    mygrid.expand();
                                    formPanel.search();
                        },
                        scope: formPanel
    }],
            keys: [{
                        key: [Ext.EventObject.ENTER],
                        handler: function() {
                                    var mygrid = Ext.getCmp('gridPanel');
                                    mygrid.expand();
                                    formPanel.search();
                        }
            }]
});

var gridPanel = new Ext.grid.GridPanel({
            id: "gridPanel",
            title: "Results",
            region: "center",
            collapsible: true,
            collapsed: false,
            store: store,
            height: 500,
            stripeRows: true,
            autoExpandColumn: 'tree_ref',
            columns: [{
                        id: "tree_ref",

                        width: 50,
                        sortable: true,
                        dataIndex: "tree_ref"

                        id: "x",

                        width: 50,
                        dataIndex: "x"
            }, {
                        id: "y",
                        header: "Lon",
                        width: 50,
                        dataIndex: "y"
    }],
            sm: selects
});

searchPanel = new Ext.Panel({
            layout: "border",
            region: "east",
            collapsible: true,
            width: 250,
            items: [formPanel, gridPanel]
})

Any help would be most appreciated.
