[Users] FeatureStore / Grid & VectorLayer

[Sascha Müller]

Hi,

I try to use grid.reconfigure(). It works for me now. Also the selection
with the Popup works.
I use the code below. Does it look the way you thought?


function load2Store(selectedLayer) {
   attributStore = new GeoExt.data.AttributeStore({
      url:
"http://localhost:8081/geoserver/wfs?service=WFS&request=DescribeFeatureType&version=1.1.0&typeName=VBL:"+
selectedLayer
   });
   attributStore.load({
      callback: function(x){
         fields = [];
         for (var i = 0; i < x.length; i++){
            fields.push(x[i].data);
         }
         finishActivating(selectedLayer);
      },
      scope: this
   });
}

function finishActivating(theLayer) {
   featureStore2 = new GeoExt.data.FeatureStore({
      layer: wfsStoreLayer,
      proxy: new GeoExt.data.ProtocolProxy({
         protocol: new OpenLayers.Protocol.WFS({
            url: 'http://localhost:8081/geoserver/wfs',
            featureType: theLayer,
            srsName: 'EPSG:21781',
            version: '1.1.0',
            featureNS: "http://www.vbl.ch",
            featurePrefix: "VBL"
         })
      })
   });
   featureStore2.reader = new GeoExt.data.FeatureReader({ totalProperty:
29,}, recordize(fields));
   gridPanel.reconfigure(featureStore2, new
Ext.grid.ColumnModel(columnize(fields)) );
   gridPanel.setTitle("Attribute des Layers:&ensp;" + theLayer);
   reloadFeatureStore();
}
        
function reloadFeatureStore() {
   featureStore2.load();
}


Thanks for your Help!
