[Users] Layer tree based on WFSCapabilitiesStore

[Denis Rykov]

Hi Matt, thanks for reply. I've modified my code, but no effect:

        <script>
        var store, layerList;
            Ext.onReady(function() {

                Ext.onReady(function() {

                    // create a new WFS capabilities store
                    store = new GeoExt.data.WFSCapabilitiesStore({
                        url:
"http://map.rostmuseum.ru/scripts/tinyows/tinyows.cgi?SERVICE=WFS&VERSION=1.0.0&REQUEST=GetCapabilities",
                        layerOptions: function() {
                            return {
                                visibility: false,
                                displayInLayerSwitcher: false,
                                strategies: [new
OpenLayers.Strategy.BBOX({ratio: 1})]
                            };
                        },
                        listeners: {
                            load: function() {
                                layerList = new GeoExt.tree.LayerContainer({
                                    text: 'All Layers',
                                    layerStore: this,
                                    leaf: false,
                                    expanded: true
                                });

                                var layerTree = new Ext.tree.TreePanel({
                                    title: 'Map Layers',
                                    renderTo: 'capgrid',
                                    root: layerList
                                });
                            }
                        }
                    });

                    store.load();
                });
            });
        </script>
