[vtk-developers] Re: Understanding vtkMultiGroupDataGroupFilter

[Bill McGrory]

FYI:
I had problems with the above patch when I ran with vtkCompositePipeline
and simple filters.

I had to pass a flag which pickeed the DATA_OBJECT, and not the
COMPOSITE_DATA_OBJECT() when in a simple loop (InSubPass = 1)

I'll post a bug report/patch as soon as I'm confident I haven't broken
anything.
