With a dict of dicts
https://github.com/romangrothausmann/ParaView_scripts/commit/3b309cc603433f02afc3e50656bd99f8b7cd0aa8#diff-2804420278bfff084788b82c715c452e
I get:

   File "/net/home/grothama/paraview/scripts/pvsm-multi.py", line 64, in main
     pvs.SetProperties(repr, **reppro[i]);
   File 
"/opt/paraview-5.3.0_GL1/lib/paraview-5.3/site-packages/paraview/simple.py", 
line 568, in SetProperties
     setattr(proxy, param, params[param])
   File 
"/opt/paraview-5.3.0_GL1/lib/paraview-5.3/site-packages/paraview/servermanager.py", 
line 317, in __setattr__
     setter(self, value)
   File 
"/opt/paraview-5.3.0_GL1/lib/paraview-5.3/site-packages/paraview/servermanager.py", 
line 2528, in setProperty
     return self.SetPropertyWithName(propName, value)
   File 
"/opt/paraview-5.3.0_GL1/lib/paraview-5.3/site-packages/paraview/servermanager.py", 
line 375, in SetPropertyWithName
     prop.SetData(arg)
   File 
"/opt/paraview-5.3.0_GL1/lib/paraview-5.3/site-packages/paraview/servermanager.py", 
line 803, in SetData
     raise RuntimeError("This property requires %d values." % 
self.GetNumberOfElements())
RuntimeError: This property requires 3 values.

Any ideas what could still be wrong?
