Why would I ever use a Chain of Responsibility over a Decorator?

Question

I\'m just reading up on the Chain of Responsibility pattern and I\'m having trouble imagining a scenario when I would prefer its use over that of decorator.

What do

Answer 1

Chain

Avoid coupling the sender of a request to its receiver by giving more than one object a chance to handle the request. Chain the receiving objects and pass the request along the chain until an object handles it.

vs

Decorator

Attach additional responsibilities to an object dynamically. Decorators provide a flexible alternative to subclassing for extending functionality.

I'd say its around the order in which things will happen. If you chain them, the will be called along the chain. With a decorator you're not guaranteed this order, only that additional responsibilities can be attached.
