[Paraview] second try -- vtk file -- scatter data -- vector field

[Utkarsh Ayachit]

I am not too sure I follow exactly the steps that you are doing. Can you
share the data as well as the sequence of actions that leads to the errors,
please? Also, what version of PAraView are you using?

Thanks
Utkarsh
