[Users] GeoExt.data.FeatureStore and layer features information

[Lluís Peinado]

Hi again, thanks a lot for your response, Andreas.
Finally I used the vector layer's events (featuresadded) with something
like:

var vecLayer = new OpenLayers.Layer.Vector("WFS", {
    eventListeners: {
        featuresadded: function() {
            var extent = vecLayer.getDataExtent()
            mapPanelWMS.map.zoomToExtent(extent);
            mapPanelWFS.map.zoomToExtent(extent);
            wms.setVisibility(true);
        }
    }});I used the example on this
page:http://workshops.opengeo.org/geoext/more_ogc/dissect.html

Regards.
