[Dune] Paraview error with vtk vector data file

[Sreejith Pulloor Kuttanikkad]

Dear All,

Here is a sample vector data file (vtkout.vtu - produced by the vtkwriter class in DUNE) attached.When i try to open it in Paraview, it produce the following error message

# Error or warning: There was a VTK Warning in file:
# /home/amy/ParaViewReleaseRoot/paraview-2.4.2/VTK/Filtering/vtkDataSetAttributes.cxx
# (937)
 vtkPointData (0x8da38b0): Can not set attribute Vectors. Incorrect
 number of components.

I couldnt figure out what is wrong witht the vtk input file. any help is
appreciated.

thanks,
Sreejith
