Page process throwing No data found error when deleting tabular form item

Question

Hi guys,
I am trying to run a page process just before the Tabular form's MRU process and it's throwing a no data found error. Here is my code:
BEGIN
     for i in 1..apex_application.g_f02.count LOOP     
          IF apex_application.g_f01(i) is not null THEN
               UPDATE STOCK
                    SET PRODUCT_QUANTITY = PRODUCT_QUANTITY+apex_application.g_f08(i)
               WHERE site_id = :P21_SITE_ID and product_id = apex_application.g_f02(i);
               COMMIT;
          END IF;
     END LOOP;
END;Here f01 is the checkbox column and the if-statement is causing the problem because if I get rid of the update statement (leaving just the commit) then it still throws the error.
When I click on a checkbox and hit delete button which fires off both this process and then MRU I get the no data found error.
Would be grateful if someone could shed some light on this. Many thanks.

You are iterating on the f02 and checking for f01 not null. That is wrong usage of the the checkbox item. Please see these links . especially the OnSubmit Process examples.

<b>Note that check boxes displayed using APEX_ITEM.CHECKBOX will only contain values in the APEX_APPLICATION arrays for those rows which are checked. Unlike other items (TEXT, TEXTAREA, and DATE_POPUP) which can contain an entry in the corresponding APEX_APPLICATION array for every row submitted, a check box will only have an entry in the APEX_APPLICATION array if it is selected.</b>
