So, is Cairngorm right for your project? Command When a View component fires an event, FrontController finds the Command class that was registered with this event and calls its aarchitecture execute. Lets see the related code of BuddyList app: It builds all view components and registers the mediators for each of them. The author of PureMVC wanted to create a framework that could have been ported to caiengorm programming languages, and this approach inadvertently delivers a product that underutilizes benefits offered by language-specific constructs.
Suppose you have 10 [Bindable] String variables in the ModelLocator. The List component the View knows about its model and is bound to it directly via its dataProvider property.
