Thank you for your help, but I get the same exceptions.

Hi Liliana,
I don't know if it will fix your problem but you don't need the &&'s in
your rules. Rules are "and"ed by default.
ie.
when
f2 : ForAllManager( id == "b2") &&
n1 : NumberWrapper(id=="n1") &&
eval(n1.getValue() < 100)
should be:
when
f2 : ForAllManager( id == "b2")
n1 : NumberWrapper(id=="n1")
eval(n1.getValue() < 100)
