At form start-up, Oracle Forms navigates to the first navigable item in the first navigable block. A When-New-Form-Instance trigger fires after the successful completion of any navigational triggers that fire during the initial navigation sequence.
This trigger does not fire when control returns to a calling form from a called form.
In a multiple-form application, this trigger does not fire when focus changes from one form to another.
