[Paraview] Python Render() has no effect

Sorry, I don't understand.

I actually have a reader derived from vtkMultiBlockDataSetAlgorithm

With python I can do the following within the python shell:

# this is atually my reader
reader = servermanager.sources.CFSreader
view = GetActiveView()
view.ViewTime = 2
view.StillRender()

voila! it works.

But even when it runs in a thread, paraview is blocked.

I finally found a solution. I use the Animation tool. Paraview
is also blocked but so far it is ok.

BTW,
http://www.vtk.org/Wiki/ParaView:AnimationTutorial
seems to be heavily outdated - It was luck that we found the Duration
property.

Anyway - I hope my workaround is sufficient.

Thanks!
