Erhm, then maybe I don't know what a model is :-) Say, I have a list of users. I would create a userList ArrayCollection and stick that into the model (bindable and all that). Now, this ArrayCollection is actually a bunch of User objects. I would therefore put the User class into the model package, and not in the vo package. Are you saying you would call this a UserVO and place it in the vo package?

That's what I do as well. Doesn't matter if it's meant for transfering data to/from server or not. They certainly don't belong in the model package though, that's where the model belongs, not data classes. If you prefer having a distinction between objects that will be sent to server and those that won't, maybe use a "data" and a "vo" package. > And also: I've read somewhere that VO's should not contain any logic, and > that you should be able to initialise all of its properties via the > constructor. What do you think? VO's usually don't contain any logic but there's no law against it AFAIK :) I never use the constructor to initialize properties. regards, Muzak ----- Original Message ----- From: "Jorge Maiquez" <[email protected]> To: <[email protected]> Sent: Thursday, August 06, 2009 2:07 PM Subject: [flexcoders] cairngorm convention: vo or model? >I have a some doubts about implementing Cairngorm correctly (and I guess MVC > in general).
