The ModelLocator is the "state bucket", and should keep your domain data, not presentation logic which the PresentationModel is responsible for.

A very standard approach would be to have the Command call the delegate, and give it a reference to a responder (IResponder), with a reference back to the model. The responder would then either do the parsing itself in the result method, or pass on the responsibility to a parser class, i would prefer the latter. That said, I'm not a big fan of the chain of classes involved in the typical Cairngorm setup. There are multiple ways of getting around it, and I'll cover an alternative soon.

What I have done now is create a result/handler function in the PM. I pass on a reference to these functions inside the event that triggers a command. The command uses a delegate to load the data. Question: should the delegate parse the data, and how does it know what is the domain model the data should be saved to? One option would be to pass a reference to the domain model in the event that triggers the command: loadDataEvent(faultHandler, resultHandler, domainModel).dispatch() Borre,

How presentation model actually relates to model locator? Should it be instantiated within model locator? Tomek Hi Borre,

really interesting slides:) I like presentation model approach and I have a question regarding this. How presentation model actually relates to model locator? Should it be instantiated within model locator?
