title: Python :issues in adding VAPI-XP parameters using CurrentTSTest object
body: <p>I know similiar question has been asked previously. Instead of hijacking the question iam raising a new one as that question didnt answer my issue. Here is the code: Iam using Python language</p>
  
  <pre><code>def Test_Main(Debug, CurrentTestSet, CurrentTSTest, CurrentRun):
   try :
     ParamFactory=CurrentTSTest
     ParamObj=ParamFactory.TestParameterFactory
     ParamAdd=ParamObj.AddItem(None)
     ParamAdd.name="Provider"
     ParamAdd.DefaultValue="XYZ"
     ParamAdd.Description="XYZ Service Provider"
     ParamAdd.Post()
     # clear output window
     TDOutput.Clear()
  </code></pre>
  
  <p>After executing the , TestParameterFactory is not working. Please can anyone let me know where iam doing wrong.  </p>
  
  <pre><code>Error] (L21: c0): Traceback (most recent call last): 
   File "&lt;Script Block &gt;", line 21, in Test_Main 
   ParamObj=ParamFactory.TestParameterFactory 
   File "C:\Python27\lib\site-packages\win32com\client\dynamic.py", line 516, in _    _getattr__ 
    raise AttributeError("%s.%s" % (self._username_, attr)) 
    AttributeError: &lt;unknown&gt;.TestParameterFactory 
  </code></pre>
