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

[Frederic Perez]

I must have done something wrong in my previous attempt with Xdmf3,
because it no longer crashes. Note that it works even without your
suggestion, as the JOIN() syntax works.

Now the problem is that, when I click "Apply", I get the following error:
"Failed to locate selected scalars. Will use image scalars by default
No scalar values found for texture input!"

Note that the same exact file works with Xdmf instead of Xdmf3.

> I think that is because Xdmf3 uses different syntax for concatenation. Try using Function="$0|$1|$2|$3|$4|$5|$6|$7|$8|$9" with the Xdmf3 reader.

>> However, this technique only works when joining a maximum of 10 different pieces of data. If I add one DataItem in the JOIN Function, ParaView crashes upon clicking "Apply".
