The tree is not synchronized with the store. It just uses it to build the
nodes. Changes in the LayerStore don’t automatically reflect in the tree. So if
you look at your code, you can see that it is trying to build a tree from an
empty store.
The layerTree code needs to execute AFTER the store has loaded.

Subject: [Users] Layer tree based on WFSCapabilitiesStore
Is it possible to build layer tree based on WFSCapabilitiesStore?
I try to make it as following:
<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})]
};
}
});
layerList = new GeoExt.tree.LayerContainer({
text: 'All Layers',
layerStore: store,
leaf: false,
expanded: true
});
var layerTree = new Ext.tree.TreePanel({
title: 'Map Layers',
renderTo: 'capgrid',
root: layerList
});
store.load();
});
});
</script>
But it not works.
