[Users] popup to show feature information

[Mario Nuñez Jimenez]

Hello,
the las thing I tried:

function createForm(feature) {
pointformPanel = new GeoExt.form.FormPanel({
    renderTo: "popup",
    protocol: new OpenLayers.Protocol.WFS({
        url: "http://192.168.215.148:8080/geoserver/wfs",
        featureType: "evento_punto_Type",
        featureNS: "http://gea.atosorigin.es/gea"
    }),
    items: [{
        xtype: "numberfield",
        name: "incidente",
        value: feature.attributes['incidente']
    }, {
        xtype: "datefield",
        name: "fecha",
        value: feature.attributes['fecha']
    }, {
        xtype: "textfield",
        name: "descripcion",
        value: feature.attributes['descripcion']
    }],
    listeners: {
        actioncomplete: function(form, action) {
            // this listener triggers when the search request
            // is complete, the OpenLayers.Protocol.Response
            // resulting from the request is available
            // in "action.response"
        }
    }
});

};
/*
formPanel.addOkButton({
    text: "aceptar",
    handler: function() {
		this.submit();
        this.close();
    },
    scope: formPanel
});
formPanel.addCancelButton({
    text: "cancelar",
    handler: function() {
        this.close();
    },
    scope: formPanel
});
*/

function createPopup(feature,form) {
    popup = new GeoExt.Popup ({
    id: 'popup',
    title: 'Geometria',
    feature: feature,
    width: 200,
    html: form.render(),
    //items: [],
    //html: getInfo(), 
    //feature.attributes['descripcion'],
    //feature.attributes['incidente'],
	//feature.attributes['fecha'],
    /*
    items:[{
		xtype: 'columnchart',
		store: getStore(),
		yField: 'hits',
		xField: 'month',
		xAxis: new Ext.chart.CategoryAxis({
			title: 'Month'
		}),
		yAxis: new Ext.chart.NumericAxis({
			title: 'Hits'
		}),
		extraStyle: {
		   xAxis: {
				labelRotation: -90
			}
		}
	    }, {html: getInfo()}],
	    */
	layout: 'fit',   
	//html: feature.getInfo(),
    collapsible: true
    });
// unselect feature when the popup is closed
popup.on({
    close: function(layer) {
            selectControl.unselect(this.feature);
    }
});
popup.render
popup.show();

}

// create popup on "featureselected"
pointLayer.events.on({
    featureselected: function(e) {
            createPopup(e.feature,createForm(e.feature));
    }
});

// create popup on "featureselected"
lineLayer.events.on({
    featureselected: function(e) {
            createPopup(e.feature);
    }
});


When I tried this, the web loaded correctly but when I select a feature on the map, it gets selected and highlighted but nothing happens, no popup opened, and I get an error that I do not understand...

ct is null
http://localhost:8080/mugagabe-webclient/js/mapfish-client-1.2/mfbase/ext/ext-all-debug.js
Line 15002

I think it is because of the renderization, I readed that this error happens because the component you want to render doesn’t exist so I still haven’t found the reason...

Any tip?
Regards.
Mario.
