View Full Version : Ext.data.Store require Ext.util.Grouper (and not use)

29 Nov 2013, 7:08 AM
ExtJs Version 4.2.2.

It seems to me that there is a little error in the requires/uses declaration of Ext.data.Store.

Ext.util.Grouper might be un requires section instead of uses section as it's used in the methode
decodeGroupers which is directly call in the constructor.

Ext.define('Ext.data.Store', {
extend: 'Ext.data.AbstractStore',

alias: 'store.store',

// Required classes must be loaded before the definition callback runs
// The class definition callback creates a dummy Store which requires that
// all the classes below have been loaded.
requires: [

uses: [

Require Ext.data.Store at the begining of my application loading cause an error "Grouper is not defined" on the following code:

if (!(config instanceof Grouper)) {

If I do not add a require to Ext.util.Grouper prior.

Thanks for the report. Can you please post a test case which reproduces the issue? You can use our Fiddle (https://fiddle.sencha.com/#home) if you like.

I don't think it's possible to do this with Fiddle because all ExtJs Framework is loaded before the application start if I'm not wrong?

The problem appear when I update my code from none Sencha Cmd managed to Sencha Cmd managed app and it seems that the order of requires has a strong influence.

Here is the little bit of code that I case the issue.

Ext.require([ 'Ext.data.Request', 'Ext.direct.*' ], function() {

Ext.define('MyApp.Application', {
name: 'MyApp',

extend: 'Ext.app.Application',

requires: [
// 'Ext.util.Grouper',

views: [

controllers: [
// list of my controller

stores: [


Common is a code package containing some Util fonction (and model, stuff like that) mostly in Singleton class. And at list one use Ext.data.Store in his initialisation.

If i remove the Ext.util.Grouper from requires (as it is here), error appear :

TypeError: invalid 'instanceof' operand Grouper

if (!(config instanceof Grouper)) {

Firebug: Store....9078708 (ligne 637)

I don't know how to reproduce this bug outside my environment.

@Psychokrameur: Same problem here. Thanks for pointing this out. Putting 'Ext.util.Grouper' in the requires section seems to fix the problem. Thank you!
