Need help Updating Records in a Report Region

Question

We have created some javascript to check a drop down used in a report region.
This is the way the report is supposed to work:
The first time the user comes to this screen he will go down the list and select a value of '1' or '2' for col2.
When col2 drop down has a value of 1 then we want to disable col3 and col4.
Then the user will click on the Submit button.
When he clicks on the Submit button then we want to set col4 to have a value of sysdate in the database table for any record where col2 had a value of 1.
The next time the user comes to this screen he will select values for col3 and col4 of the records that col2 had a value of 2 (meaning col3 and col4 are enabled)
This works fine if there is only one record in the report region.
The problem is when we have more than one record.
for example:
Say we have two records...
for record1 the user selects '1' for col2 and for record2 the user selects '2' for col2.
When the user clicks on the Submit button col3 and col4 get disabled and col4 gets set to sysdate for record1, while col3 and col4 remain available but empty (because the user has not made a selection for these columns at this point) for record2.
When the user comes back to this screen he now selects a value for col3 and picks a date for col4 for record2. When he clicks on the Submit button the value for col3 and the date entered in col4 for record2 should get updated in the database table and it is but the col3 value and the col4 date is being inverted with record1's data for some reason.
Can you please tell me how to fix this?
This is what the user has selected on the screen:
(COL2) (COL3) (COL4)
Requested? Granted? Response Date
Record1 NO - 13-APR-09
Record2 YES YES 20-APR-09
After the user clicks on the Submit button this is how the screen displays it back:
(COL2) (COL3) (COL4)
Requested? Granted? Response Date
Record1 NO YES 20-APR-09
Record2 YES N/A 13-APR-09
I am including the code from my update staement below:
DECLARE
A_ID NUMBER;
requested NUMBER;
grnted NUMBER;
respdate DATE;
f01 = AID ID
f02 = REQUESTED YES OR NO
F03 = GRANTED YES OR NO
F04 = RESPONSE DATE
BEGIN
FOR i IN 1..HTMLDB_APPLICATION.G_F01.COUNT LOOP
BEGIN
A_ID      := HTMLDB_APPLICATION.G_F01(i); -- this is hidden
requested := HTMLDB_APPLICATION.G_F02(i); -- (YES or NO)
grnted := HTMLDB_APPLICATION.G_F03(i); -- (YES or NO)
respdate := to_date(HTMLDB_APPLICATION.G_F04(i),'MM/DD/YYYY');
EXCEPTION
WHEN OTHERS THEN
A_ID      := HTMLDB_APPLICATION.G_F01(i); -- this is hidden
requested := HTMLDB_APPLICATION.G_F02(i); -- (YES or NO)
grnted := 3; -- (YES or NO)
respdate := sysdate;
END;
UPDATE TBL_AIT
SET b_requested_id = requested,
b_granted_id = grnted,
b_response_date = respdate
WHERE ait_id = A_ID;
END LOOP;
END;

Hi,
Any disabled items are not submitted with the page - therefore, your f03 and f04 collections would be one value short. This is a browser feature rather than an Apex feature.
You can get around this by enabling all items before the submit takes place. Have a look at: Re: A better method of handling tabular forms with variable column type? This is for disabling items mainly, but includes an enableItems() javascript function that should help you.
