Oops, my finger slipped, and I hit send!

What I was trying to say is that this application will have several different components, eg navigator, title bar, area for the discussion threads etc. Each of these will need to know about the underlying model. Ideally, I would like to make the components reuseable, so I am looking for a good way to link them to the model.

My first thought was to simply add setModel: methods to each component, but then it ocurred to me that perhaps the framework has some sort of model propagation system, or a data bus that components subscribe to.

If not, is my simple approach the way others would do it, or is there a better way?

Cheers AN
