[vtkusers] vtkStreamingDemandDrivenPipeline Error!!!

[Alex Malyushytskyy]

Solution depends on what you really want:
- if you need PolyData - you might want to extract cells as polygonal data
( read Robert's comment )
- if you just want to display untsructured grid  datasets you read you
might want
to use vtkDataSetMapper instead of vtkPolyDataMapper
If you might want to extract part of unstructured grid , check
vtkExtractUnstructuredGrid,
or vtkContourGrid.
