OK, I have done some looking around and found a possible solution. I am not sure if its pure Cairngorm or MVC but it seem to work for me so here we go
You can have more than 1 Model. You can have as many as you require grouping you data in logical collections. These should always be Bindable.
Then in my case You have a creationComplete event in you main application file that tells a command to load data in the usual Cairngorm way. This data is then passed to and ArrayCollection in the Model
What I am then doing (rightly or wrongly) is adding an event listener in the main app file that listens for the ArrayCollectio to change (CollectionEvent.COLLECTION_CHANGE) and then trigger another event.
I suppose you could get more complex and have a Boolean variable in the Model that just states if data was loaded correct and the app file listens for that to change.
I guess I am treating the concept of Models as not just a place to store your data but also all variables that need to be globally accessed. As I said I have now idea if this is proper MVC or the correct use of Cairngorm but it works for me.
I hope that’s clear and not just a load of garbage ;-)
