[Paraview] Problems with user defined filter

[Utkarsh Ayachit]

So you have written a vtk filter, then I am assuming you have some main() in
which you are creating a VTK-pipeline to use this filter? Are you setting up
the inputs correctly? Try calling Update() directly on  the filter, does
that result in calling of your RequestData() method?
