Hi Davide,
I need access to your file to understand your class structure
and see what could be wrong.
In the code generated automatically, the initialisation of
the classes holding the TClonesArray may be incorrect.
You may have to add the static TClonesArray pointer
as it is shown in $ROOTSYS/test/Event.h
