BgOverlay and FTDCollection at DDSim #10

Closed Voutsi closed 8 years ago

Voutsi commented 8 years ago

when running BgOverlay before SplitCollectionsByLayer, and therefore feeding BgOverlay with FTDCollection


A runtime error occured - (uncaught exception): lcio::Exception: DDPlanarDigiProcessor::processEvent(): no surface found for cellID : system:1,side:0,layer:5,module:13,sensor:0 Marlin will have to be terminated, sorry.


On the other hand, if we run first SplitCollectionByLayer which creates the FTD_PIXELCollection and FTD_STRIPCollection then:


A runtime error occured - (uncaught exception): lcio::EventException: LCEventImpl::addCollection() name already exists: FTD_STRIPCollection Marlin will have to be terminated, sorry.

Fixed by Shaojun - simply not consistent collection names
