    There are some issues with the data package in the current PR, including this bug. These issues will be fixed before the GA.

    I had the same error. This is because the proxy-property in the Ext.data.Batch is never set. As a workaround you can add this to the constructor:

    Code:
    if (config.hasOwnProperty) {
      this.proxy = config.proxy;
    }

    Hi,

    I would be possible to have more code because I can't understand how to use this indication?

    Thank you.

    You have to change the contructor of Ext.data.Batch in your sencha-js file. I did it for the sencha-touch-all-debug.js. You will find the definition of this class at line 21456. There you have to change the constructor like this:

    Code:
    constructor: function(config) {
        var me = this;
    
        // aflx
        if (config.hasOwnProperty) {
            this.proxy = config.proxy;
        }
    
        me.mixins.observable.constructor.call(me, config);
        me.operations = [];
    },
    Hopefully this will be fixed with the next update. Sencha announced several updates to the data package.
