Summary

0003772: vtkMergeDataObjectFilter broken?

Description

Hi there,
I am trying to update some code that I wrote ages
ago that works fine with VTK 4.x, but breaks with
current CVS. I am storing geometry and scalar
data in different files and I'm using the
vtkMergeDataObjectFilter to help combine them.
The particular code looks something like this:

//-------------
vtkMergeDataObjectFilter *merge = vtkMergeDataObjectFilter::New();
vtkUnstructuredGridReader *readGeom = vtkUnstructuredGridReader::New();
readGeom->SetFileName(geomfilename);

readAttr = vtkDataObjectReader::New();
readAttr->SetFileName(datafilename);
readAttr->SetFieldDataName("scalarvar");

// # combine data and build scalars
merge->SetInput((vtkDataSet *) readGeom->GetOutput());
merge->SetDataObject(readAttr->GetOutput());
//-------------

When it hits the last line of code, VTK says:
ERROR: In /usr/local/src/vtk/VTK/Filtering/vtkAlgorithm.cxx, line 679
vtkMergeDataObjectFilter (0x523820): Attempt to connect input port index 1 for an algorithm with 1 input ports.

I just downloaded and built VTK 4, and the code runs fine -- can anybody suggest a reason why it fails with recent CVS?

Attached is a simple python script and two data files that exhibit this problem (works ok with VTK 4 though). The problem also occurs with TCL and C++ programs.
