Generate QueryCommand from RepositoryRecord

Hi

I am porting an app written with the ActiveRecord pattern to Repository pattern (Pakala 2.1).

The old app used, for example, Order.GetUpdateCommand()... to generate a QueryCommand that can be used in Transactions.

however, with the Repository, I cannot seem to find a way to do this.

Once I made changes to an Order object, how can I generate a QueryCommand (an Update, Insert, etc.) out of that "dumb" object (that implements RepositoryRecord<T>)???Is there a way?

Thanks!
