extjs 4.0.7, code:

var languageStore = new Ext.data.Store({
    autoLoad: true,
    storeId: 'languagesStore',
    proxy: {
        type: 'ajax',
        url: 'languages.json.php',
        reader: {
            type: 'json',
            root: 'languages'
        }
    },
    fields: [{name: 'id', type: 'int'}, {name: 'name', type: 'string'}]
});


var languageCombobox = new Ext.form.ComboBox({
	fieldLabel: 'Язык',
    id: 'language-combo',
  	store: languageStore,
    disabled: false,
    valueField: 'id',
    displayField: 'name',
    emptyText: 'Выберите страну…',
    editable: false,
    listeners:
    {
    	select:
    	{
    		fn: function(combo, value)
    		{
    			var cc = Ext.getCmp('country-combo');
    			cc.clearValue();
    			if (cc.isDisabled())
    				cc.setDisabled(false);
    			cc.getStore().load({params: {languageId: combo.getValue()}});
    		}
    	}
    }
});


var countryStore = new Ext.data.Store({
    storeId: 'countriesStore',
    proxy: {
        type: 'ajax',
        url: 'countries.json.php',
        reader: {
            type: 'json',
            root: 'countries'
        }
    },
    fields: [{name: 'id', type: 'int'}, {name: 'name', type: 'string'}]
});


var countryCombobox = new Ext.form.ComboBox({
	fieldLabel: 'Страна',
   	id: 'country-combo',
   	store: countryStore,
    disabled: true,
    valueField: 'id',
    displayField: 'name',
    emptyText: 'Выберите страну…',
    queryMode: 'local',
    editable: false
});

Json answer look like this:

{"countries":[{"id":"1","name":"Great Britain"},{"id":"2","name":"USA"}],"total":2}

Can I hide this loading panel?
