Hi...
Usually "NoneType" Error means an Object is not loaded in into the database, or you may have specified a wrong module name in your code..
Scenario 1:
Consider test.py & text.xml are having your Object creation & Object view creations respectively... Check whether have you imported "test.py" in your "__init__.py"
Scenario 2:
Check the object name defined in py is same as in xml views.... There are chances are having spelling mistakes in either of your files...
Can you please paste code where you getting error ?
