XDMF - 8 byte precision UInt is broken
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
This problem relates to opening XDMF files in Paraview 4.1.
Support for XDMF DataItem elements of NumberType=UInt with Precision="8" is broken when using topology stored in an external data file with Format="Binary".
I suspect the driver is trying to interpret the binary value as a signed int rather than an unsigned int.
Using NumberType=Int works OK with Precision="8" and is a satisfatory work around for now.
This might be a trivial fix if it is just a case of correctly casting the data.
