(from reference section 3.8) | the Factory method gets only called if the referenced context variable, the factory method is defined for, is not yet bound to a value. In your case the context variable is "customerList". Once this context variable is set to a value, the factory won't be called anymore, when "customerList" gets referenced additional times. In contrast, the method annotated with @unwrap gets called EVERY time the manager component with the name "customerList" is referenced.
