Update process does not work on Tabular Form

Question

Hello,
I have 2 tabular forms on one page, which are using manual update processes.
First form is created using wizard, and therefore works perfectly.
The update process is as follows:
DECLARE
  lc_string VARCHAR2(4000);
BEGIN
  FOR i IN 1..APEX_APPLICATION.G_f01.COUNT
  LOOP
     lc_string := lc_string|| '[' ||APEX_APPLICATION.G_f*03*(i) || '|' || APEX_APPLICATION.G_f*04*(i) || ']';
  END LOOP;
  --Database processing using the concatenated string here
END;Second form is created manually, using the following code:
SELECT apex_item.checkbox (30,
                           '#ROWNUM#',
                           'onclick="highlight_row(this,' || '#ROWNUM#'|| ')"',
                           NULL,
                           'f30_' || '#ROWNUM#'
                          ) delete_checkbox,
       CATALOG_ID,
          apex_item.hidden (31, CATALOG_ID)
       || apex_item.text (32,
                          LANG,
                          80,
                          100,
                          'style="width:100px"',
                          'f32_' || '#ROWNUM#'
       || apex_item.hidden (33, wwv_flow_item.md5 (LANG, DESCRIPTION)) LANG,
       apex_item.text (34,
                       DESCRIPTION,
                       80,
                       100,
                       'style="width:255px"',
                       'f34_' || '#ROWNUM#'
                      ) DESCRIPTION
  FROM V_CATALOGS
UNION ALL
SELECT     apex_item.checkbox
                          (30,
                           TO_NUMBER(9900 + LEVEL),
                           'onclick="highlight_row(this,' || '#ROWNUM#' || ')"',
                           NULL,
                           'f30_' || TO_NUMBER (9900 + LEVEL)
                          ) delete_checkbox,
           NULL,
              apex_item.hidden (31, NULL)
           || apex_item.text (32,
                              NULL,
                              80,
                              100,
                              'style="width:100px"',
                              'f32_' || TO_NUMBER (9900 + LEVEL)
           || apex_item.hidden (33, NULL) LANG,
           apex_item.text
                                           (34,
                                            NULL,
                                            80,
                                            100,
                                            'style="width:255px" '  ,
                                            'f34_'
                                            || TO_NUMBER (9900 + LEVEL)
                                           ) DESCRIPTION
      FROM DUAL
     WHERE :P18_TEMP = 'ADD_ROWS1'
CONNECT BY LEVEL <= 1However, the update process does not work on this form.
I created it using the first one as an example, but with the id's of the second form:
DECLARE
  lc_string VARCHAR2(4000);
BEGIN
  FOR i IN 1..APEX_APPLICATION.G_f*30*.COUNT
  LOOP
     lc_string := lc_string|| '[' ||APEX_APPLICATION.G_f*32*(i) || '|' || APEX_APPLICATION.G_f*34*(i) || ']';
  END LOOP;
  --Database processing using the concatenated string here
END;Also, both forms are opening in a modal pop-up dialog window.
I use a Dialog Region plug-in for that.
Please advise, what is causing a problem with update?

Sloger,
if this is your tabular form
SELECT apex_item.checkbox (30,
...and this is your update statement
FOR i IN 1..APEX_APPLICATION.G_f*30*.COUNT
...Then you will only ever update records that have been checked. Unchecked checkboxes are not passed back in the global array. You need to have a hidden column with the ID's for the record and loop through that when you are updating/inserting. That is why the built in tabular form has a MRU and a MRD. the MRU loops through the hidden ID column. The MRD loops through the checkbox.
