[Paraview-developers] error when trying to hide a sphere in a python script....

[Utkarsh Ayachit]

Josh,

Can you narrow down the error to specific pv.Hide() call? The  error
is popping up due to something calling the Hide with arguments that
have not been setup properly. Let's isolate that and we can then trace
backwards from there. If you want to send me the reset of the code +
data, feel free to do that off line.
