[Zehvogel]

BEGINRELEASENOTES

• Added a Geant4TVUserParticleHandler that can utilise an arbitrary tracking volume as introduced in Various issues implemented (Issue #371, #373, #378) #384

ENDRELEASENOTES

fixes #1302

It compiles but when I try to use it the following happens

Geant4UI         INFO  +++ ParticleHandler> Install Geant4 control directory:/ddg4/ParticleHandler/

So I guess I still need to add something somewhere or my local setup is weird? The error is emitted here:

DD4hep/DDCore/src/Grammar.cpp

Line 192 in c3b305c

dd4hep::except("BasicGrammar","FAILED to look up non existent registry: %016llX [%s]",

but I don't know what any of this grammar stuff is or is supposed to do... is there any documentation?

Can you share or link to the geometry with the tracking volume?

Yes I pushed it here now:
