Custom tabular form for multi-row not saving data

Question

Ok, before anyone asks, yes, I did read the how-to:-)
I have a custom tabular form, which I did cause I need to use popups and the popups that you can use in the wizard tabular form does not display the text but rather the value underneath it.
It returns data rather nicely and when I go and update values I can tell it is changing the fields underneath. I put a process in that will display the values in text fields on the form (for one row only) and I see them changing from what is already there and with the proper values.
However, when I do that the data that is displayed then gets reverted back to what it was previous to the update but reports that the process was successful.
I have also tried to insert but that is basically doing the same thing. Can anyone guide me.
SQL to generate the tablular form...
SELECT x.sak_release_db
, x.sak_object
, x.sak_release
, x.sak_participant
, x.sak_csr
FROM
(SELECT htmldb_item.hidden(1,sak_release_db) sak_release_db
, htmldb_item.popupkey_from_query(2, sak_object,
'SELECT b.nam_schema||''.''||a.nam_technical as table_name , b.sak_object
FROM system_object a
, database_table b
WHERE a.sak_object = b.sak_object') as sak_object
, htmldb_item.hidden(4,sak_release) sak_release
, htmldb_item.popupkey_from_query(5, sak_participant,
'SELECT nam_first || '' '' || nam_last as name, sak_participant FROM co_participant') sak_participant
, htmldb_item.popupkey_from_query(7, sak_csr,
'SELECT external_id|| ''-''||id_split as co, sak_csr FROM co') sak_csr
FROM release_db_xref
UNION ALL
SELECT htmldb_item.hidden(1,NULL) sak_release_db
, htmldb_item.popupkey_from_query(2, NULL,
'SELECT b.nam_schema||''.''||a.nam_technical as table_name , b.sak_object

'SELECT nam_first || '' '' || nam_last as name, sak_participant FROM co_participant') sak_participant
, htmldb_item.popupkey_from_query(7, NULL,
'SELECT external_id|| ''-''||id_split as co, sak_csr FROM co') sak_csr
FROM dual) x
Process to verify that I have the correct global fields: (Type: PL/SQL anonymous block, Process Point: On Submit - After Computations and Validations)
begin
:P3_2 := replace(htmldb_application.g_f02(1),'%'||'null%',NULL);
:P3_5 := replace(htmldb_application.g_f05(1),'%'||'null%',NULL);
:P3_7 := replace(htmldb_application.g_f07(1),'%'||'null%',NULL);
end;
Process to do the insert/update. Note, I hardcoded the value in the where clause but I was originally using the global value for g_f01 (i also tried putting a commit in there for fun) (Type: PL/SQL anonymous block, Process Point: On Submit - After Computations and Validations):
-- Update the RELEASE_DB_XREF table
FOR i IN 1..htmldb_application.g_f01.count
LOOP
IF htmldb_application.g_f01(i) IS NOT NULL THEN
UPDATE release_db_xref
SET sak_object = replace(htmldb_application.g_f02(i),'%'||'null%',NULL)
, sak_participant = replace(htmldb_application.g_f05(i),'%'||'null%',NULL)
, sak_csr = replace(htmldb_application.g_f07(i),'%'||'null%',NULL)
WHERE sak_release_db = 22;
ELSE
IF htmldb_application.g_f02(i) IS NOT NULL THEN
INSERT INTO release_db_xref
(sak_object
,sak_release
,sak_participant
,sak_csr)
VALUES
(replace(htmldb_application.g_f02(i),'%'||'null%',NULL)
,htmldb_application.g_f04(i)
,replace(htmldb_application.g_f05(i),'%'||'null%',NULL)
,replace(htmldb_application.g_f07(i),'%'||'null%',NULL));
END IF;
END IF;
END LOOP;

Florian,
Checkboxes are different from other HTML form items. When you have a text box for example, there's always a value send to the server when submitting. Even if that value is NULL. When you have a checkbox however, you only get the value if the checkbox is checked. It's not posted to the server when it is not checked. That's the general behavior of HTML forms and not specific to Oracle HTML DB.
When working with tabular forms in HTML DB, you can access your form values using the htmldb_application.g_f0x arrays. Now if you have for example 10 rows in your form, then you'll get ten elements in your array for text boxes, select lists, etc. For checkboxes however you'll only get as many elements as you have rows checked. If I read your update and insert code correctly, you're trying to use the checkbox arrays the same way you use the arrays based on other item types. My recommendation would be to use Yes/No select lists instead of checkboxes or at least use select lists initially to get it working and then work on properly processing the checkboxes.
Some general information about working with checkboxes in tabuar forms can be found here:

Hope this helps,
