Most of the seam example applications (all cept wiki) combine @DataModel with ScopeType.SESSION. This seems contrary to the seam philosophy of minimizing session maintained data.  This would appear to be particularly problematic if large query results were being maintained.

I am building a system that will have dozens upon dozens of different query - list - create/retrieve/update/delete applications. 

What is the right approach query - list @DataModal with regard to memory management?
