Summary0012994: vtkXMLMultiBlockDataWriter does not write names for leaf nodes of the multiblock dataset
DescriptionThe following code will assign the name for 0 block, but will not write this name into vtu file:
============================================
vtkNew<vtkUnstructuredGrid> ugrid;
vtkNew<vtkMultiBlockDataSet> mb;
mb->SetNumberOfBlocks( 1 );
mb->SetBlock( 0, ugrid.GetPointer() );
mb->GetMetaData( 0 )->Set(vtkCompositeDataSet::NAME(), "My Material 1");
mb->GetMetaData( 0 )->Print( std::cout ); // for debuggin to see the name
vtkXMLMultiBlockDataWriter *writer = vtkXMLMultiBlockDataWriter::New();
writer->SetInput( mb.GetPointer() );
writer->SetFileName("test.vtm");
writer->Write();
============================================
The problem is inside vtkXMLMultiBlockDataWriter.cxx, int vtkXMLMultiBlockDataWriter::WriteComposite method iterates over multiblock data set items, and writes names only for vtkCompositeDataSet datasets.

The fix looks easy, I am attaching the fixed file.

VTK Reader & Paraview support reading of leaf dataset names correctly, so the problem is only in writer.

Thanks,
Nikolay
