I don't usually make an entire class Bindable on a single event like you
posted earlier, so I'm not 100% on this, but I'm pretty sure it won't
auto-generate that event for you in your setters, so you would have to
dispatch it manually, with the side effect that all of your other bindings
would fire as well. I usually go the route of using the default Bindable
event and then using describeType in my updateAll to generate the
propertyChangeEvent so that I can still fire individual bindings without the
overhead.
I also cache the result of the describeType so that it will only happen once
on each qualified class name as that method can be pretty heavy.
