    Default readRecords fails with empty json objects on iOS

    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
    Code:
    TypeError: 'undefined' is not an object
    Fix:
