[Paraview] state-file does not contain 2D texture if assigned by python

[Grothausmann, Roman Dr.]

After some hours of searching I found an answer that sadly was not linked to the 
question:
http://www.paraview.org/pipermail/paraview/2012-March/024261.html

The code below run as a macro in paraview shows a plane with a texture.
However, saving the state in a *.pvsm either by code or within the GUI does not 
save the texture and its assignment.

What is missing to save the texture and its assignment in a state file?

import paraview.simple as pvs

plane1 = pvs.Plane(guiName="xz-plane")
dp = pvs.GetDisplayProperties(plane1)
dp.Representation = 'Surface With Edges'

texProxy = pvs.servermanager.CreateProxy("textures", "ImageTexture")
texProxy.GetProperty("FileName").SetElement(0, "texture.png")
texProxy.UpdateVTKObjects()

dp.Texture= texProxy
print dp.Texture
pvs.Render()

pvs.servermanager.SaveState("test.pvsm")
