Hi,

I found some bizarre behavior in Geant4. Namely, I am trying to get information about initial step number and initial parent ID of registered particle in novice example # 2, using “sensitive detector” approach. For that I modified next file: ExN02TrackerSD.cc. Modification is given below:

  newHit->SetPos      (aStep->GetPostStepPoint()->GetPosition());
  if ( (aStep->GetTrack()->GetParentID() == 0)&&
       (aStep->GetTrack()->GetCurrentStepNumber() == 1) )
  {
    G4cout << "====> ExN02TrackerSD: (0) parentID: "<< aStep->GetTrack()->GetParentID()
           << " StepNo: "  << aStep->GetTrack()->GetCurrentStepNumber()
           <<  G4endl;
    exit (-10);
  }
  trackerCollection->insert( newHit );

In principle, the executable for this example should be stopped right after first simulated particle, as it will be satisfy the case condition. In reality, the program just runs till the last simulated particle. I have tried to do the same modification in novice example # 4; however I have got the same results as for example # 2. How I have to modify code to get information that I would like to get?

I am using Scientific Linux 4 with gcc 4.5 and Geant4.8.3 version.
