Translating VSM to BC4J

Question

Hi,
We dowloaded de VSM example couple days ago and then we started to think how to map those patterns to the BC4J objects.
We already have Application Modules playing the role of the Managers, so each one of our database entities has it's own View Object and an Application Module with some logic for insert, update and delete.
Also, we have an application module per Use Case. It's like a controller but it doesn't talks directly with the view layer. To do that, we have another application module (the Controller), extended from the Use Case Application Module. So, we have one Controller per Use Case.
The Controller has methods to handle events generated by the view layer and provide the correct refresh at the view layer. These methods, like in the VSM, return an UserResponse Object. Among another parameters we put BC4J objects, like the ViewObject.
We use hashmaps as value objects to pass attributes from the view layer to the control layer. These value objects are passed as a parameter to the controllers's event handlers.
What do you think about this architecture? Any visible flaw? Any suggestions?
Thanks in advance.

Have you seen my recent article on using BC4J to implement collections of Value Objects for MVC applications? Why not just use the BC4J RowSet and Row (or optionally, our type-safe Row you can have generated for you) instead of having to repopulate a HashMap ?
