Thanks, Andrew. This makes good sense. However, if I only run one single facade method, and previous old state doesn't bug me (all variables are re-initialized before used), can such "temporal" use of fields be justified?
Imagine I have a chain of methods inside a SLSB.
a calls b, b calls c, c calls d, etc.
Facade method receives a parameter. I need to use that parameter down the chain of execution. Should I put that parameter in each method declaration? Ouch ... Doesn't look very appealing, don't you think?
