[Users] Dynamic fields in FeatureStore

[gbrun]

I found something interesting to fetch attributes names dynamically. I  
would like to use an AttributesStore. So I tried to use it first in a  
quite simple way but I think, I'm missing an important configuration  
stuff. Here is my code:

	var attributeStore = new GeoExt.data.AttributeStore({
			url:  
'http://192.168.168.199:81/geoserver/wfs?SERVICE=WFS&VERSION=1.0.0&REQUEST=DescribeFeatureType&typename=wfs:unit_pay'
	});
	
	var gridattributes = new Ext.grid.GridPanel({
			title: "Feature Attributes",
			store: attributeStore,
			cm: new Ext.grid.ColumnModel([
				{id: "name", header: "Name", dataIndex: "name", sortable: true},
				{id: "type", header: "Type", dataIndex: "type", sortable: true}
			]),
			sm: new Ext.grid.RowSelectionModel({singleSelect:true}),
			autoExpandColumn: "name",
			stripeRows: true,
			renderTo: document.body,
			height: 300,
			width: 350
	});

In fact, no DescribeFeatureType request is launched watching in FireBug. I  
tested the DescribeFeatureType request directly trough OpenLayers and it  
works (using a code I found in an old email from the OpenLayers  
mailing-list).

So there really is something that I don't understand with the  
AttributesStore configuration!

Could anyone help me please?
