I'm trying to make a spanish framework :)

Yes, the cursor is temporal, created for data object

You are right, but data object is responsible to make data available
The biz object don't care about session, but data session linked to bizobject does
I have:

Interface (container base class)
|
|---> BizObj (custom) ----> Fields(custom)
|
|----->Data (custom) ------> session (session)

I make data as custom for visual editing.

Yes, but every grid is on distinct interface object, and interface class is responsible for instantiate the biz obj.
I want to reuse the interface objects, and when I drop an interface at design time on a form, the interface class have all the info that need to work.
Data object is responsible for open tables. Is that right?
If you have multiple sessions data object don't need to check if a table is already open, or problems with buffer mode.
