[Paraview] unknown properties returned by ListProperties?

Roman,

Looking at your original problem with the error:


   File "/opt/paraview-5.3.0_GL1/lib/paraview-5.3/site-packages/paraview/servermanager.py",
line 375, in SetPropertyWithName
     prop.SetData(arg)
   File "/opt/paraview-5.3.0_GL1/lib/paraview-5.3/site-packages/paraview/servermanager.py",
line 1296, in SetData
     self.SMProperty.AddProxy(value_proxy)
TypeError: AddProxy argument 1: method requires a VTK object


You are hitting this when attempting to set the DataAxesGrid, which is a
ProxyProperty. In your dictionary, this entry has value 'None', but it
looks like setting a property to value 'None' is not handled correctly in
servermanager.py. As a workaround, I suggest filtering out properties from
your dictionary that have 'None' as a value, i.e., do not add those
property values to your dictionary.

HTH,
Cory
