I am getting frm :40737 because go_block

Question

Hello World,
I have a form with master block and details , the detail block as a tabular.
I want the detail block to track the changes on the master , like if the user updated on a particular item on the master the detail keep the username and date.
i put the below code as a POST-TEXT-ITEM trigger on the item on the master
DECLARE
V_TOT_RECORD NUMBER := 1;
V_COUNT NUMBER := 1;
BEGIN
V_TOT_RECORD := GET_BLOCK_PROPERTY('BLK2', QUERY_HITS);
GO_BLOCK('BLK2');
FIRST_RECORD;
WHILE V_COUNT <= V_TOT_RECORD LOOP
IF :BLK2.CFT_PROC_STATUS IS NULL THEN
     :blk2.cft_serial:=V_COUNT;
     :BLK2.CFT_PROC_STATUS:=:BLK1.CFU_STATUS;
     :BLK2.CFT_USER_ID:=:BLK1.CFU_USER_ID;
     :BLK2.CFT_DATE:=:BLK1.CFU_DATE;
END IF ;
IF V_COUNT = V_TOT_RECORD THEN
EXIT;
END IF;
IF V_COUNT = V_TOT_RECORD THEN
EXIT;
ELSE
NEXT_RECORD;
END IF;
V_COUNT := V_COUNT + 1;
END LOOP;
END;
but i am getting this error
FRM:40737 illegal restricted procedure GO_BLOCK in POST-TEXT-ITEM trigger.

Take a look at the Forms Help on the Post-Text-Item trigger to see which built-ins are allowed. Calling a Restricted built-in like GO_BLOCK in certain triggers could cause endless loops and other adverse side-affects. You could use a Zero (0) millisecond Timer to execute the restricted built-in(s) as this is a common work-around, but I would recommend you look into other alternatives to tracking these changes that don't required you to navigate between blocks.
Why do you need to have the Detail block keep track of changes in the Master block? Also, it is always helpful to at least include your Forms version when asking a question. :)
