Answer 1

You're having a problem because you are mixing injectables and non injectables in your constructor. The general rules for injection that will save you tons of heartache and keep your code clean are:

1. Injectables can ask for other injectables in their constructor, but not for newables.

2. Newables can ask for other newables in their constructor but not for injectables.

Injectables are service type objects, ie objects that do work such as a CreditCardProcessor, MusicPlayer, etc.

Newables are value type objects such as CreditCard, Song, etc.
