Hello all,

I’m writing a plugin using the base structure of the vtkXdmfReader.h/cxx + readers\_xdmf2.xml. I’ve just modified the files to expose different names to the SM xml and to modify the extension to myxdmf. Unfortunately when reading a myxdmf (an xdmf that loads as required in pv only with a different extension) PV crushes.

Any hints would be more than helpful at this point 🙂

Running through a debugger to see why it crashes is your best bet. Make sure you’re using a Debug (or RelWithDebInfo) build of ParaView and the plugin.
