All of my views are bound to models. I have data specific models and models that drive views (kind of like the ViewHelper class). so the event would result in a change to the view model which would update the view.
The way I have it setup is there is an AppModelLocator application wide data models (like my user object are bound here) I then have models for application states (like login and home). These models have some specific variables to drive the views. Strict Cairngorm would have you put these variable in a ViewHelper. I also (although not strick MVC) use mx:Binding statements to link the source view to the model when the event would do nothing more than update the variable (for example when the user selects an item in a grid I bind grid selected item to model selected item.) --Sean --- In [email protected], "Douglas Knudsen" <[EMAIL PROTECTED]> wrote: > > I too use Cairngorm and would suggest it.
