[Paraview] Re: Multiple pieces in UnstructuredGrid

[Craig Warren]

I still can't get CellData for more than one piece to diaply using  
UnstructuredGrid in Paraview with the XML format. However, it works  
with the legacy format. I would still prefer to use the xml format,  
so any suggestions are most welcome. This is the legacy file that  
works, and below it the xml file that doesn't.
