[Paraview] python changes 4.0/4.1 to 4.3?

[Anton Shterenlikht]

I've a script that used to work ok on 4.0 and 4.1,
but now something is wrong with the colours.
Has anything changed between 4.0/4.1 to 4.3 to make

DataRepresentation3.DiffuseColor = [1.0, 1.0, 0.0]

not understood?


The full script:

Is there anything wrong in this script for 4.3?

Many thanks
