[Paraview] help with a simple script?

[Sebastien Jourdain]

Hi Celia,

I think you found a bug, but I think I have something for you.
The following method should clear the view/layouts.

Seb

$ def clearLayout():
... pxm = servermanager.ProxyManager()

... for layout in GetLayouts():

...   pxm.UnRegisterProxy("layouts", layout[0], GetLayouts()[layout])
