Only output parameters should be returned. Try just
return True
It would be helpful if the makepy generated event prototypes indicated which
parms are treated as output, something like:
# def OnSomethingOrOther(self, arg1=defaultNamedNotOptArg,
arg2=defaultNamedNotOptArg, arg3=defaultNamedNotOptArg):
# return arg3
I might try to implement that when I have some time.
