[vtkusers] vtkMultiGroupDataSet composed from vtkStructuredGridSource->GetOutput()

[Bill McGrory]

I'm using the cvs version of vtk.

I'm trying to construct a vtkMultiBlockDataSet where each of the Blocks
is constructed in a custom build vtkStructuredGridSource Producer.

However, I can't seem to get it to work.
I've dug into the vtkCompositeDataPipeline trying to decypher the
process, and see what I'm doing wrong, but I can't see how this can ever
work, based upon my minimal understanding.

My question is this.

Should I be able to do what I'm trying to do, or is this feature not
supported.

Note: I can successfully visualize a vtkMultiBlockDataSet if I fill it
with hand-built vtkStructuredGrid's. I can also visualize I single
vtkStructuredGrid created through my vtkStructuredGridSource. So I don't
think it's a problem with either of those two components, but more, how
the two components interact.


Thanks for any comments
