readRecords fails with empty json objects on iOS

[pdm]

Sencha Touch version tested:

• 1.1.1

Platform tested against:

• iOS 5.x
• iOS 5 Simulator
• Chrome

Description:

• when returning an empty element in json, readRecords in Ext.data.Reader fails

Chrome seems to be tolerant of this, but iOS with phonegap/cordova isn't. Throws

TypeError: 'undefined' is not an object

This seems to be fixed in Sencha Touch 2
