filterBy not working..

That object in the console will get updated as long as you haven't expanded. So if you console.log(store) and the store finishes being loaded before you expand the store then you will see the updated store.

You need to get a number or string or boolean to see if the store has loaded, I usually do

console.log(store.getCount());

That will not update as the store loads.

I have this and it works for me:

Store:

var listaMatStore = new Ext.data.Store ({
	autoLoad: true,
	model: 'listaMatModel',
	sorters: 'DescMaterial',
    getGroupString : function(record) {
        // Group by the last name
        return record.get('DescMaterial')[0];
    },
	proxy:
	{
		type: 'rest',
		url: 'data/materiales.txt',
		reader:
		{
			type: 'json',
			root : 'root'
		}
	}
});

List:

var listaMat = new Ext.List({	id: 'listaMat',
	store: listaMatStore,
        grouped: true,
	itemTpl:
	'<div class="materialItem">'+
		'<div class="item-img"><img src="resources/images/shopping_cart.png" width="50" height="50"></div>'+
		'<div style="float:left; width:90%;">'+
		'<div class="list-codigo">'+
			'<span>{CodMaterial}&nbsp;&nbsp;&nbsp;{CodUMedida}-{UMedidaRendimiendo}</span>'+
			'<br />'+
			'{DescMaterial}'+
		'</div>'+
		'<div class="list-peso">'+
			'<span>Peso: {Peso} KG&nbsp;&nbsp;&nbsp;Precio: {PrecioUnit} PEN</span>'+
			'<br />'+
			'<span>Stock: {Stock}&nbsp;UN</span>'+
		'</div>'+
		'</div>'+
	'</div>',
	listeners: {
		'render': function (thisComponent) {
			var desc = formBuscaMat.getValues().descripcion;
			if(desc){
				thisComponent.getStore().load();
				thisComponent.getStore().filter('DescMaterial',desc);
			}
			else{
				thisComponent.getStore().load();
			}
		}
	}
});

I may be misunderstanding the life cycle of the store but I thought filterBy determines what gets loaded when you call store.load();

So, If we do this:

store.filterBy(function(item,id){
//If we found the correct item
return true;
}, this);

store.load();

The store should now have the records filtered by the criteria.

Is this a correct assumption?

If I am correct, then why should the store already have items in its data before applying the filter?
