A short update. I've temporarily fixed the problem. Turned out from time to time it did get no pointer to the material table...But what's still mysterious is that the reflectivity was initialized being 1.0 in the constructor. How could it be reset to 0 if there's no pointer? This was why I didn't check weather there's a pointer to material table found; I thought if there's no such a pointer, the reflectivity should have remain 1.0, which was what it started with...
Anyway, now my code runs well with the "else"
PropertyPointer = aMaterialPropertiesTable->GetProperty("REFLECTIVITY"); if (PropertyPointer) theReflectivity = PropertyPointer->Value(thePhotonMomentum); else theReflectivity = 1.0;;
