Update process with APEX_APPLICATION

Question

Hi Friends,
I have a APEX page made with APEX_ITEM. I created the below process [which will run on a Button Click].
my issue is : Process completes with out updating the Database showing the Process Success Message. I do not see any errors. I checked the documentation and other examples for usage of APEX_APPLICATION and could not find any mistake.
All fXX columns are rightly displayed on the page and are mapped correctly in Insert and Update stmts of the below process.
Any suggestions to debug will help..
<Code here>
DECLARE
v_cp_id NUMBER;
v_cp_line NUMBER;
BEGIN
v_cp_id:=nv('P32_CP_ID');
for i in 1..apex_application.g_f02.count
loop
if ( apex_application.g_f02(i) is not null) then
update CP_OTHER_TRANSACTION_DETAILS
set BUSINESS_TRANSACTION_NAME = apex_application.g_f03(i),
DESCRIPTION = apex_application.g_f04(i),
TRANSACTIONS_PER_PEAK_HOUR = apex_application.g_f05(i),
SLA = apex_application.g_f06(i),
CSD_LINK = apex_application.g_f07(i)
where CAP_PLAN_ID = apex_application.g_f01(i) and LINE_NO = apex_application.g_f02(i);
ELSE
IF ( apex_application.g_f03(i) is NOT null) then
     SELECT NVL(MAX(LINE_NO),0)+1 INTO v_cp_line FROM CP_OTHER_TRANSACTION_DETAILS;
insert into CP_OTHER_TRANSACTION_DETAILS
(CAP_PLAN_ID,
     LINE_NO,
BUSINESS_TRANSACTION_NAME,
DESCRIPTION,
TRANSACTIONS_PER_PEAK_HOUR,
SLA,
CSD_LINK
values
(v_cp_id, v_cp_line,
apex_application.g_f03(i),
apex_application.g_f04(i),
apex_application.g_f05(i),
apex_application.g_f06(i),
apex_application.g_f07(i) );
end if;
end if;
end loop;
COMMIT;
END;
</Code here>
Thanks ..

Having looked at your app, I would suggest you recreate this page using a Tabular Form based on a Table/View. This feature will automatically take care of adding new rows, updates etc., as well as those all important record lock mechanisms!
As for what you have at the moment, the problem lies in the hidden elements on the form - the PL/SQL process was never dropping into the loop because apex_application.g_f02.count is zero! This is because the columns are flagged as "not shown".
To include these items, modify the SQL in your report to concatenate the items together with the first displayable item on the page.
Therefore something like this:
select apex_item.hidden(1,CAP_PLAN_ID) ||
         apex_item.hidden(2,LINE_NO) ||
         apex_item.text(3,BUSINESS_TRANSACTION_NAME) BUSINESS_TRANSACTION_NAME,
apex_item.text(4,DESCRIPTION) DESCRIPTION
.NOTE - the first two fields are concatenated to the business_transaction_name column, but remain hidden when the page is displayed!
Hope that makes sense!
