[vtkusers] vtkMergeDataObjectFilter broken?

[Chris Want]

Hi there,

I wrote a tcl program with vtk 3.2
that uses vtkMergeDataObjectFilter with
vtkFieldDataToAttributeDataFilter to
combine the geometry in one file with the
scalars in another file (field data).
Using the latest vtk from cvs this
program no longer works, and it gives
the error:

ERROR: In 
/usr/local/src/vtk/VTK/Graphics/vtkFieldDataToAttributeDataFilter.cxx, 
line 329
vtkFieldDataToAttributeDataFilter (0x81b38f0): Can't find 
array/component requested

I can't find any modern examples that
use this filter, and the one old vtk 3.2
example that used to work (mergeDataObject.tcl)
no longer works and issues the same error.

Can anybody recommend a workaround?

Regards,
