Python trace bug for heterogeneous multiblock datasets
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Load a multiblock dataset with only unstructured grid leafs. Paraview sees a multiblock dataset containing only unstructured grid data, so it creates an unstructured grid display. Next you enable more blocks, so that multiblock dataset now contains unstructured grid and polydata leafs. Save the python trace now. The trace script records volume rendering properties of the unstructured grid display. When the trace script is replayed, paraview sees the multiblock dataset has unstructured grid and polydata leafs, so it creates a geometry display instead of an unstructured grid display. The geometry display lacks the volume rendering properties.
You could reproduce this bug using an extract block filter with an input multiblock dataset that contains unstructured grid and polydata.
