[vtkusers] blank render window in VTK 6.0 (git)

[Juan Cardelino]

Dear all,
             I tried to move to vtk git version (pulled today), and
after migrating all the code (mainly SetInput->SetInputData), every
single vtk application stopped rendering. See for instance this simple
program:
https://iie.fing.edu.uy/avn/gral/trunk/src/vtk/Cone.cpp
https://iie.fing.edu.uy/avn/gral/trunk/src/vtk/CMakelists.txt (it
includes other stuff, but it is still useful to see how I call VTK)
My programs were working in windows, mac and linux with VTK 5.9 and
5.10. I've checked the migration guide and googled it but without any
luck so far.
Has anyone experienced a similar behaviour?
Best,
        Juan
