[Paraview] multi block crash

[John Doe]

Hello,

Could someone verify the proper multiblock format for a vtm file:

This one crashes:
<?xml version="1.0"?>
<VTKFile type="vtkMultiBlockDataSet" version="0.1"
byte_order="LittleEndian" compressor="vtkZLibDataCompressor">
  <vtkMultiBlockDataSet>
    <DataSet group="0" dataset="0" file="mos_2d_0.vtu"/>
    <DataSet group="1" dataset="1" file="mos_2d_1.vtu"/>
    <DataSet group="2" dataset="2" file="mos_2d_2.vtu"/>
    <DataSet group="3" dataset="3" file="mos_2d_3.vtu"/>
  </vtkMultiBlockDataSet>
</VTKFile>

with:

paraview: /home/jsanchez/ParaView3/VTK/IO/vtkXMLDataReader.cxx:347:
virtual void vtkXMLDataReader::SetupOutputData(): Assertion
`this->NumberOfPointArrays ==
this->PointDataArraySelection->GetNumberOfArraysEnabled()' failed.
Abort

This one shows no data:
<?xml version="1.0"?>
<VTKFile type="vtkMultiBlockDataSet" version="0.1"
byte_order="LittleEndian" compressor="vtkZLibDataCompressor">
  <vtkMultiBlockDataSet>
    <DataSet index="0" file="mos_2d_0.vtu"/>
    <DataSet index="1" file="mos_2d_1.vtu"/>
    <DataSet index="2" file="mos_2d_2.vtu"/>
    <DataSet index="3" file="mos_2d_3.vtu"/>
  </vtkMultiBlockDataSet>
</VTKFile>

Loading the individual files works fine.  I could have sworn the one
that crashes worked fine yesterday.

I am using the latest CVS.

Thanks,

Juan
