[Paraview] Bug in XDMF reader ?

[houssen]

Just to clarify, the scenario that makes problem is : select all cells, 
go to selection inspector, visualize (in 3D viewer) values on cells and 
/ or points (this triggers errors).
My understanding is that both xdmf (OK and KO) are valid and should 
work. OK.xdmf works (whatever PV version), but, KO.xdmf do not (whatever 
PV version).
The problem appears when attribute names differ on different grids : 
this looks (not sure) like a bug to me.

With PV5.0.0 + default XDMF reader (which should be XDMF2 if I 
understand correctly), I get :
Warning: In 
/scratch/ParaView-v5.0.0-source/VTK/Rendering/Label/vtkLabeledDataMapper.cxx, 
line 439
vtkLabeledDataMapper (0x36cc600): Could not find label array 
(NodeValues) in input.
Warning: In 
/scratch/ParaView-v5.0.0-source/VTK/Rendering/Label/vtkLabeledDataMapper.cxx, 
line 439
vtkLabeledDataMapper (0x36cc600): Could not find label array (NodeVal) 
in input.

Note : I tested with all point and cell values, only node values 
triggers error, cell values "do nothing".

With PV5.0.0 + XDMF3 reader, I get:
'Content' not found in itemProperties in XdmfArray::populateItem
Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt. You must
reimplement QApplication::notify() and catch all exceptions there.
terminate called after throwing an instance of 'XdmfError'
   what():  'Content' not found in itemProperties in 
XdmfArray::populateItem

With PV4.0.1 + default XDMF reader (which should be XDMF2 if I 
understand correctly), I get :
Warning: In 
/scratch/ParaView-v4.0.1-source/VTK/Rendering/Label/vtkLabeledDataMapper.cxx, 
line 442
vtkLabeledDataMapper (0x97f2140): Could not find label array (CellVal)

in input.

Note : I tested with all point and cell values, only CellVal and 
NodeVal triggers error, NodesValues and CellValues are visualized 
correctly.
