[Paraview] help with a simple script?

Tue Nov 20 14:47:19 EST 2012

Hi Celia,

The weird thing is that you don't have any object in your layout.

{('ViewLayout1', '2178'): >>>HERE<<< , ('ViewLayout1', '275'): >>>HERE<<< }

This create the issue that you are seeing. Although, what you/we try to
solve might not be the real issue.
So I don't really know what is going on when you load your state on your
machine.

Seb
