//The Lead Store, this version will simply load with mock JSON data.
Ext.define("PocketCRM.store.Leads", {
    extend: "Ext.data.Store",
    requires: "Ext.data.proxy.LocalStorage",

    config: {

        model: "PocketCRM.model.Lead",

        //Fetch the data from the custom Apex controller method 
        //which will return a simple list of Leads as JSON on load.  
        data: {
            !Leads
        },

        //Create a grouping; be certain to use a field with content or you'll get errors!
        groupField: "Status",
        groupDir: "ASC",

        //Create additional sorts for within the Group.
        sorters: [{
            property: 'LastName',
