[SOLVED] After post trigger go to the specific item. (Oracle Forms 10g)

Question

I have this layout
http://img339.imageshack.us/img339/975/capturetbo.png
and a post trigger insert and update
                IF  :item1 IS NULL
          AND :item3 IS NOT NULL THEN
                    alert_id := FIND_ALERT('blank_alert');
                    SET_ALERT_PROPERTY(alert_id,ALERT_MESSAGE_TEXT,'Item3 must have a value.');
                    v_alert := SHOW_ALERT(alert_id);          
                    RAISE Form_trigger_Failure;
          END IF;My problem was as it fires, the cursor will be on the item1.
I've already use
SET_ITEM_INSTANCE_PROPERTY
NEXT_ITEM
GO_ITEMbut it was all illegal. The cursor must be in the item3.
Don't question me why I do not set the item3 to required and why post triggers.
It is just that. It is the requirement.
Any bright Idea? Thanks!
And even when-validate-item triggers. It must be post triggers.
Is it possible? Thanks.

Answer 1

POST-TRIGGER
DECLARE
timer_id                       TIMER;
one_second                       NUMBER := 1000;
BEGIN
<validations . . .>
timer_id := CREATE_TIMER('timer', one_second,NO_REPEAT);
END;WHEN-TIMER-EXPIRED
GO-ITEMBright idea! Million thanks!
Note: I have an typo error in my code. It should be
IF  :item3 IS NULL
          AND :item1 IS NOT NULL THENAgain. Thanks!
