Operation.commitRecords fails, wrong Ext.util.MixedCollection init?

[Zyphrax]

REQUIRED INFORMATION

Ext version tested:

• Touch 2.0-pr2

Browser versions tested against:

• Chrome

Description:

• I'm working on a store-to-store system for syncing data between localStorage and my rest services.
• Somewhere deep in sencha code a call is made to commitRecords on the operation class:

commitRecords: function (serverRecords) {
     var me = this,
                    mc, index, clientRecords, serverRec, clientRec;

      if (!me.actionSkipSyncRe.test(me.action)) {
                clientRecords = me.records;
                if (clientRecords && clientRecords.length) {
                       mc = Ext.create('Ext.util.MixedCollection', true, function(r) {return r.getId();});
                       mc.addAll(clientRecords);

• The following line is causing a javascript error

mc = Ext.create('Ext.util.MixedCollection', true, function(r) {return r.getId();});

• It (indirectly) calls the constructor of Ext.mixin.Observable and finds that "true" isn't a valid config object.

constructor: function(config) {
        if (config) {
            if ('listeners' in config) {

- The javascript error I get is that you can't use in on a boolean.

Work around:

// Sencha bug: boolean is not a valid config object
Ext.define('Ext.mixin.Hacks', {
override: 'Ext.mixin.Observable',
constructor: function(config) {
        if (config && Ext.isObject(config)) {
            if ('listeners' in config) {
                ....
