Hm, I tried the port_index method, but it still crashes when run from
Paraview. My filter works fine from c++ (see Example.cxx). Would you
mind taking a look to see if you can find the discrepancy between how
I setup the pipeline in the c++ code vs in the XML? One thing I
noticed is that in the Input Editor that opens when I begin to apply
the plugin, the input ports are not listed in the same (correct) order
as they are in the xml (specified by port_index). Could that point to
the problem? If so, why is it happening?
