Material properties not found when adding G4OpticalPhysics to the physics list

[Hiitsaso]

I have gammas going through a volume with mesh_mat material. When adding G4OpticalPhysics to the physics list I get the following error:

*** G4Exception : mat202
      issued by : G4MaterialPropertiesTable::GetConstProperty()
Constant Material Property Index 11 not found.
*** Fatal Exception *** core dump ***

It seems that it is failing to find some (optical?) properties of the mesh_mat material. I have traced the error to this section of the code:

   G4MaterialPropertiesTable* xenon_pt = GXe_properties(pressure, temperature, sc_yield, e_lifetime);
   return n4::material_properties()
     .add("ABSLENGTH"                   , optPhotRangeE_, abs_length)
     .NEW("WORK_FUNCTION"               ,                 stainless_wf)
     .NEW("OP_PHOTOELECTRIC_PROBABILITY",                 photoe_p)
     .copy_from(xenon_pt, {
       "SCINTILLATIONCOMPONENT1",
       "SCINTILLATIONCOMPONENT2"})
     .copy_NEW_from(xenon_pt, {
       "SCINTILLATIONTIMECONSTANT1",
       "SCINTILLATIONTIMECONSTANT2",
       "SCINTILLATIONYIELD",
       "SCINTILLATIONYIELD1",
       "SCINTILLATIONYIELD2",
       "RESOLUTIONSCALE",
       "ATTACHMENT"})
     .done();

and I suspect that it comes from the .copy_form and/or .copy_NEW_from attributes.

I suspect the bug comes from an error in xenon_pt itself that we found while refactoring your code. Do you have the latest version of your code uploaded somewhere?

You can find the code here. To reproduce the error just run just run 1000.

The issue was resolved by updating the nain4 version to v0.1.8.
