How to create a Form based on a dynamic table?

Question

Hello,
The Select statement below creates a table based on a string (string is a value of an item):
select * from table (pkg_util.fn_get_table (:P18_VALUE))I need to create a region on a page with a Form based on this table.
I was able to create a Report, but not a Form.
I need to create a Form, which would return updated string to the page item.
How can I solve this please?

Hello Gentlemen,
I have created a Tabular Form, based on APEX_ITEM API, as you suggested, here is the code below:
SELECT apex_item.checkbox (30,
                           CATALOG_ID,
                           'onclick="highlight_row(this,' || ROWNUM || ')"',
                           NULL,
                           'f30_' || LPAD (ROWNUM, 4, '0')
                          ) delete_checkbox,
       CATALOG_ID,
          apex_item.hidden (31, CATALOG_ID)
       || apex_item.text (32,
                          LANG,
                          80,
                          100,
                          'style="width:100px"',
                          'f32_' || LPAD (ROWNUM, 4, '0')
       || apex_item.hidden (33, wwv_flow_item.md5 (LANG, DESCRIPTION)) LANG,
       apex_item.text (34,
                       DESCRIPTION,
                       80,
                       100,
                       'style="width:255px"',
                       'f34_' || LPAD (ROWNUM, 4, '0')
                      ) DESCRIPTION
  FROM V_SYSTEM_CATALOGS_PR
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 :P180_TEMP = 'ADD_ROWS1'
CONNECT BY LEVEL <= 1however, the update process doe not work on that 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;Can you please see what's wrong with the code?
Also, I tried to set a temp. item with the value, to see if the process returns something, like that:
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;
     :p18_temp := lc_string;
END;and it did not work.
Also, it is the second Tabular Form on this page. The first one is created using wizard, and it works perfect, with the same update process:
DECLARE
  lc_string VARCHAR2(4000);
BEGIN
  FOR i IN 1..APEX_APPLICATION.G_f*01*.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;Also, both forms are opening in a modal pop-up dialog window.
I use a Dialog Region plug-in for that.
May be this is causing a problem?
But still, the first form works fine!?
