short transactions in DataForms

Götz
Hi,
I have downloaded the latest version from VW. I want to change the behavior in the generate DataForms. How can I force short transactions? On the Dataform is no accept Button, only the commit one. Now I will modified more than one row and if I press the commit button the following process started: session begin; update; update; insert; .....session commit or rollback. I think the trigger is a single row buffer and I need an other one?!  Who can give me a short example?

Yours faithfully
Götz

You probably want to look at Glorp for object/relational mapping - the  
framework used by the Dataforms is not being actively worked on

Thank you Mr Robertson.

Now it's my first time to get starting with glorp. I love the DataModeler from the
ObjectLens. I hope, I get the same graphical assistance....?!

The bad news: there's no GUI tool for Glorp.  The good news:

-- Glorp is under active development
-- There's an ActiveRecord layer for Glorp


I've done a few screencasts on Glorp:
