OAF - Best way to extend VO

If you cannot extend any existing VO then the best way is to create a stacklayout and place your items inside it using jdeveloper, create an AM and VO which you can wire up with the item. Use personalization to add a stackLayout and extend the stacklayout which you had created using jdeveloper. You can add a region using personalization only from 11.5.10 CU2.
