[vtkusers] Problem with reader->Update();

[Arun Kharghoria]

Dear All:

I am using VTK4.2 with Borland Builder 5.0.

I am trying the following code and getting an
exception ('Exception Object Address:0xC0FEE6')in the
line 
   
   mapper->SetInput(reader->GetOutput());

and it is pointing to 

    USEFACET.H routine.

I'll be glad if somebody could give me an idea to get
around with this problem. (I am also giving the
'test.vtk' data file at the end of the mail).

Thanks a lot.

****code**

  vtkDataSetReader               *reader;
  vtkDataSetMapper               *mapper;
  vtkActor                       *outlineActor;      

  reader = vtkDataSetReader::New();
  reader->SetFileName("test.vtk");

  mapper = vtkDataSetMapper::New();
  mapper->SetInput(reader->GetOutput());
