I had a question about the Decorator Pattern: in Head First Pattern Designs, the pointer to the Component instance inside each Decorator is defined in the concrete Decorator classes. Why not in the abstract Decorator class? It's been a while since I programmed in Java, so maybe this isn't possible, but I'm sure it must be.
