REQUIRED INFORMATION

Ext version tested:

Ext 4.1 rev RC2

Browser versions tested against:

IE8
FF11 (firebug 1.9)

DOCTYPE tested against:

Description:

In my Model I have a field called 'length', Using this in a grid column is fine, but when binding to a form the whole form stays empty.

Steps to reproduce the problem:

Have a Store with a field 'length'
Have a form with an input and dataIndex 'length'
Do a form.loadRecord() with a record from the store

The result that was expected:

The form shows the data from the record

The result that occurs instead:

The complete form is empty

Test Case:
Modified the form-grid Example:

Code:

Ext.require([
    'Ext.form.*',
    'Ext.data.*',
    'Ext.grid.Panel',
    'Ext.layout.container.Column'
]);


Ext.onReady(function(){

    Ext.QuickTips.init();

    var bd = Ext.getBody();
