Good morning,

I've been studying hits shared between tracks using the GBLTracks collection. When I do this, the method in TrackUtils no longer works. The relevant issues are in lines 780-800 of the "isSharedHit".

Essentially, the problem has to do with casting the TrackerHit as a HelicalTrackHit. I have no problem using this method when I use TrackerHit as opposed to HelicalTrackHit. 

Is there a reason that the method throws an error when I recast the TrackerHit using GBLTracks? Is anyone else using this method or could I change it to use TrackerHits? 

Any clarification in this would be extremely helpful.
