Jerome,

I changed SetInput(...GetOutput()) to SetInputConnection(...GetOutputPort())
but I still get a bunch of these errors:

vtkStreamingDemandDrivenPipeline (0x8eede78): Algorithm
vtkGraphAlgorithm(0x8eebee8) returned failure for request: vtkInformation
(0x8ee9ef0)

The FillInputPortInformation I had just taken from another filter - I don't
know what that part was doing either. I removed it. The updated files are
here:

Thanks,

David
