I need to do this because there would be a lot of unused data in the

I have to check there if the data is already loaded anyway, so that

Sure. Just to reiterate UMEvent extends CairngormEvent.
Cool.
I think support for mixing event types is actually a recent change to the
Command class provided by UM Cainrgorm (which your commands then subclass).
If your version of the code is more than about a week old I would suggest
pulling down the latest.

I think the problem is that the current flex framework architecture
doesn't conceptually work well with Cairngorm.
There's too much logic encapsulated into the view.
Ideally you would like to drive the entire app via the model.
It would be ideal if your model was managing how many windows are
The whole point of MVC is that the model knows *nothing* about the view.
Which is one of the reasons UM is a great extension to Cairngorm.

Agreed
- Model has no reference to the view Classes.
But it can still drive the creation of the view.
For example, you might have an arrayCollection, the amount of items in
the arrayCollection determine the amount of windows on display..
The items within the arrayCollection may be the
I'm not using it so I can't comment on the implementation, but the callbacks
are definitely a good idea. Letting each individual view know when whatever
it has kicked off has either succeeded or failed in a standard way (whatever
that may be) is great.
It'd be nice if we could get an AsyncToken
I assume that when a new window is opened you have an event that
causes the data it needs to be loaded into the model locator. And you
will probably have a check to see if the data is already loaded so you
don't load it twice.
Just keep track in the model of how many users there are for that
Hi Josh,
The implementation is roughly as follows. One of the additions is a
Callbacks class which implements IResponder, so on a basic level its just a
container for a result and fault handler. Rather than your custom events
