ColdBox, ColdFusion, LightWire, Object Oriented Design (OOP)
As we push ahead with our app using ColdBox and LightWire, we have been configuring our Dependency Injection as we go. DI is one of those things I'm pretty certain I see the benefit to, but I'm not sure how sold on it I am. At this point, we may only have 50 to 60 CFCs so perhaps we're just not deep enough in to see the real profit yet. The only real advantage I've seen to date is having all of our dependencies spelled out in one configuration file (with the exception of the stuff you are auto-wiring). Other than that, I don't know that I have really saved any code. That being said, I don't have any circular dependencies, and my dependency levels don't get much more than 2 or 3 levels deep right now so maybe I just need to be patient.
