iPhone: Object is null in another view when set with values read from XML

I am reading an XML from and parsing the data in one viewController class. When I try to access the object in another view, it appears as null. The NSMutableArray is set with values in the earlier view. I need these values to set a picker view. Could you please let me know where am I going wrong? I have attached the code below: The value of testArray is null in the other view.
