I'm vague about I should be using in a sort of a simulation app where the user is presented with a web page that presents data from multiple domains and provides a variety of interactions that touch multiple domains.
In this case it is a real estate simulation where the UI presentation shows the user data about houses, offer to buy and sell, status of the users negotiations, etc, information about "state of the world" and that kind of thing. A fair amount of ajax going on in the page as well.
Can I just have a controller which is not associated with a particular domain and then just provide all the different objects? Maybe use a command object to deal with actions coming back from the user?
Hopefully this quesiton is not too vague for a coherent answer, I'm just looking for suggestions on the high level approach.
Yes, you can have a controller which does not directly correlate to a specific domain. For instance you could create a DashboardController. The use of command objects is up to you and your needs, but you can use Domain instance in the above controller just like any other controller.
