Trying to fetch picker wheel values using attributes is not returning any values on appium version 1.2.2

find_element(:class, “UIAPickerWheel”).attribute(“values”) is not returning all picker values on appium server 1.2.2.
I could get this working on appium server 1.2.0. Any help would be appreciated.
Attached is the server log for reference.
