Hello,

My questions are related to vtkMultiBlockDataSet :

- In a vtm file it’s possible to name each block using the xml attribut `name`, is there a way to name the `vtkMultiBlockDataSet` root object so that it’ll appear in the Paraview Multi-Block inspector ?
- In Paraview, i’ve a created a programmation filter which outputs a vtkMultiBlockDataSet. The output is good when i do not change the name of items like  
that :  
`some_node.GetMetaData(0).Set(vtk.vtkMultiBlockDataSet.NAME(),"My text")`  
If i do so, the output is a real mess, the subblock are not is the right class

Any idea ?

The first question is not related to Paraview.
