Hi Riku,
Welcome to the list. Cairngorm asserts that "state" and "model" are synonymous. One approach to manage the state of a view, is to maintain state variables in the ModelLocator that are directly bound to state properties in a view. By utilizing binding, the displayed state of the view is automatically updated, when a change is made to the associated state variable in the ModelLocator. You can see a simple f2b3 example here:
http://www.cflex.net/showfiledetails.cfm?ChannelID=1&Object=File&objectID=422
In regards to your question concerning commands, the example above also demonstrates how to dispatch a simple CairngormEvent, which the FrontController uses to execute a command.
Personally, as well, I experienced some confusion while creating my first Cairngorm-based Flex application. My advice is to stick with it. Read the articles again and let the concepts sink-in some more. Cairngorm may still seem a little complicated to you right now, but believe me, in no time you will come to appreciate its' simplicity.
Best Wishes,
Tim Hoff
