[Paraview] [Non-DoD Source] XDMF makes paraview crash with JOIN

[Frederic Perez]

Hi,

I have been looking closely into this problem in the past few days,
and I have never been able to make the Xdmf3 reader to JOIN any HDF5
data. Neither with the JOIN() syntax nor with the "$0|$1" one. At
least to populate an Attribute's DataItem. The Xdmf2 reader works
until 10 elements are joined.

To go further in this investigation, could someone point me to the
source code of the Xdmf3 reader, specifically where the "joining"
takes place?

Cheers
Fred
