What's the best practice for auto-updating a view based on changes in the model. Is it appropriate to bind to model properties or is their a better way?

    In most cases, the recommended way is:

    A Model dispatches a custom event with a VO as a payload when its data changes.
    A Mediator listens for that event and passes the VO on to its View by accessing View’s API.

    Useful reads:

    and, of course, lots and lots of forum-discussions on this topic :

    Thank you all for the responses. I'm going with the VO approach right now, mainly because I am in learning mode. Once I get a bit more comfortable with the framework, I will employ the PM design and see what's doin

    Again, thanks
