Issue loading json store to form in extjs 4.0

Question

I have the following code. I'm trying to create the store via json. I can see that firebug calls the json but this data is not loading the form. This is working with a local instance of the of model. So i confident that the panel that contains "formJobSummary" is working. The issue is somewhere on the store.

Ext.define('user', {
    extend: 'Ext.data.Model'
    fields: ['quotedPrice']
});

var store = Ext.create('Ext.data.Store', {
    model: 'user',
    proxy: {
        type: 'ajax',
        url: '/data/users.js',
        reader: {
            type: 'json',
            root: 'user'
        }
    },
    autoLoad: true
});


Ext.define('MyApp.view.MyPanel', {
    extend: 'MyApp.view.ui.MyPanel',
    initComponent: function () {
        var me = this;
        me.callParent(arguments);
        var form = Ext.getCmp('formJobSummary'); 
        form.loadRecord(store);
    }
});

Json '/data/users.js'

{
    "success":"true",
    "user": [{
        "quotedPrice":"12345"
    }]
}

for completeness, here is view.ui

Ext.define('MyApp.view.ui.MyPanel', {
    extend: 'Ext.panel.Panel',

    height: 600,
    width: 950,
    layout: {
        align: 'stretch',
        type: 'vbox'
    },
    title: 'JobPanel',

    initComponent: function() {
        var me = this;

        Ext.applyIf(me, {
            items: [
                {
                    xtype: 'tabpanel',

Answer 1

The problem is in setting record to form. First of all, loadRecord accepts record, not store. Next problem is that, the store is not loaded when you call loadRecord. Below is modified store definition which solves problem. Basically you should bind to load event of the store, to be sure that records have been loaded.

var store = Ext.create('Ext.data.Store', {
    model: 'user',
    proxy: {
        type: 'ajax',
        url: 'data2.json',
        reader: {
            type: 'json',
            root: 'user'
        }
    },
    autoLoad: true,
    listeners: {
        load: function() {
            var form = Ext.getCmp('formJobSummary'); 
            form.loadRecord(store.data.first());
        }
    }
});
