Add multiple rows in detail form in master detail form

Question

Hi,
I have a master detail form to enter survey responses. The master form captures the participant information and the detail form will carry the survey responses. After entering the master record, I need the detail rows to be populated with the survey questions stored in another table. The respondent will then update the response for each row in the detail form. Only after all the responses are filled out, clicking the save button should the detail records be committed.
Is there a good way to achieve this.
Thanks in advance

Sorry, did not check OTN until this afternoon. Busy checking existing Apex pages on my project :)
Our region to populate the tabular form has the tabular form fields defined as Display As Text (saves state). Non-enterable fields are defined as "Display as Text (saves state)". A tabular form results from these definitions.
Because Apex won't generate code to handle multipe row tabluar form inserts we wrote our own as an After Submit PL/SQL process, something like
DECLARE
  v_rows_found_n number;
BEGIN
  --code for debugging
  raise_application_error(-20000,'Hello World: '||
    apex_application.g_f03(12)||':'||
    apex_application.g_f04(12)||':'||
    apex_application.g_f05(12)||':'||
  for i in 1..apex_application.g_f01.count loop
    BEGIN
      --attempt update first
      update whatever
         set field4 = apex_application.g_f05(i)
       where field1 = apex_application.g_f03(i)
         and field2 = apex_application.g_f04(i)
         and field3 = apex_application.g_f02(i);
      v_rows_found_n := SQL%rowcount;
    --if no rows were updated perform an insert
    if (v_rows_found_n = 0) then
       insert into oe_metric_values(
         field1,         --1
         field2,         --2
         field3,         --3
         field4          --4
      values(
        apex_application.g_f02(i), --1: field1
        apex_application.g_f03(i), --3: field2
        apex_application.g_f04(i), --2: field3
        apex_application.g_f05(i)  --4: field4
    end if; --did update operate on any rows?
  --exception
  --  when others then
  --    raise_application_error(-20000,'i'||':'||
  --      apex_application.g_f03(i)||':'||
  --      apex_application.g_f04(i)||':'||
  --      apex_application.g_f05(i)||':'||
    END; --internal loop block
  end loop; --loop through tabular form submit elements
end; --pl/sql blockI had to get the identities of the f01, f02 etc. identifiers by looking at the HTML code in the rendered form because Apex assigns those values as it will. Anytime the column display changes in any way i have to go through and make sure the identifers have not changed.
Hope this helps.
