[Paraview] [help] Volume rendering in ParaviewWeb

[le Anh Dung]

Hello everybody,
I tried to write a plugin (renderVol.py attached) to do a volume  
rendering in PWConsole of ParaviewWeb.
When I tried to set the ColorArrayName or Representation (functions in  
renderVol.py), I always got this:

Traceback (most recent call last):
   File "<jsonrpc>", line 147, in handle_request
   File "/root/ParaViewWeb/WebServer/PW-work/plugins/renderVol.py",  
line 24, in setColorArrayName
     dp.ColorArrayName = a
   File

setProperty
     return self.SetPropertyWithName(propName, value)
   File

   File  
"/root/ParaView3/build-paraview3/Utilities/VTKPythonWrapping/site-packages/paraview/servermanager.py", line 681, in  
SetData
     raise ValueError("Expected a tuple of 2 values or a string.")
ValueError: Expected a tuple of 2 values or a string.

execute_command_on_plugin {'error': {'message': 'Expected a tuple of 2  
values or a string.', 'name': 'ValueError'}, 'result': None, 'id': 1}

It'll work fine if I set them fix in my renderVol.py
examples:
    dp.ColorArrayName = 'MetaImage'
or dp.Representation = 'Volume'
But I want to set them manualy in PWConsole and then get that error :(
Could anyone please help me ? :)

Thank you in advance.
Have a nice day :)
