Bug 480711 Fixed Reflectivity MatDB bug where the add button broke.
The recent changes caused, for some unknown reason, the
ReflectivityModel Item to no longer receive the IMaterialsDatabase
service. This addresses that problem by catching the service in the core
and reconfiguring the XMLMaterialsDatabase to register directly with an
activator.
