Error (ORA-01403) saveing data form a report with apex_item items

Question

Hi all,
I've a problem saveing data that's inserted into a report which I created using apex_item items. Reproducing the exact issue on apex.oracle.com will take me a lot of time, and I don't know if I really can reproduce this matter... So I hope I can explain my problem clearly enough, here...
The global story of the application is that its an application used for measureing objects. For these objects there are templates, with default properties. When measureing an object, the user must fill in those properties for the object. The report is build dynamicly, becouse each object has different properties and each property could be of an other kind (number, text, list, counter [=number field with add and substract buttons], and date). Depending on the type of the property, the report has to show an other item to fill.
The query for constructing this report is like this:
select defprop.proptyp_id,
apex_item.hidden(41,defprop.id) defprop_id,
defprop.nam,
decode(proptyp.id,
                1, apex_item.text(p_idx=>42,p_value=>''||

object_instance obj,
property_type proptyp
where defprop.stdobjver_id = obj.stdobjver_id
and defprop.proptyp_id = proptyp.id
and obj.id = :P2200_ID_INVThis report works fine. Depending on the type of the property it shows a numberic field, text field, selectlist (with right values), counter field or date field.
If the default property is set to a 'CONSTANT' value, the last known value is filled in.
With a javascript I check the numberic field value and achieve the counterfield to add or substract values when 'plus' or 'minus' is clicked.
This javascript is placed in the field 'Execute when Page Loads' in the page properties in APEX. Here is the code:
/*Execute when page loads*/
/*Allow only numbers */
number_elem = $('input[name=f42].case5_num');
number_elem.keypress(function(event) {
  if (event.which && (event.which < 46 || event.which > 57 || event.which == 47) && event.keyCode != 8) {
      event.preventDefault();
  if (event.which == 46 && $(this).val().indexOf('.') != -1) {
      event.preventDefault();
//for mouse events, remove any non numeric characters
number_elem.bind('mouseup mousedown mouseleave', function(event) {
   this.value = this.value.replace(/[^0-9]/g, '');
/* Subtract Button */
$('a[name="sub_f42"]').click( function() {
  number_elem = $(this).siblings('input[name=f42].case5_num');
  currVal = number_elem.val();
if ( isNaN( currVal) ){
   elemVal = 0;
else {
   elemVal = Number(currVal);
if (elemVal > 0)
     number_elem.val(elemVal-1);
else
{ elemVal = 0; }
/* Add Button */
$('a[name="add_f02"]').click( function() {
  number_elem = $(this).siblings('input[name=f42].case5_num');
  currVal = number_elem.val();
if ( isNaN( currVal) ){
   elemVal = 0;
else {
   elemVal = Number(currVal);
number_elem.val(elemVal+1);
});Those two codes makes my report works fine. So far I'm happy. But now I want the data, which the user fills in the items, to be saved.
So I created a process that should do this for me (it wil run after the user hits a button), here is the code:
declare
     v_objmet_id number := 0;     
begin
     select measurment_seq.nextval
     into v_objmet_id
     from dual;
     insert into measurment
     ( id
     , obj_id
     , dat
     values
     ( v_objmet_id
     , :P2200_ID_INV
     , :P2200_METDAT_INV
     /*Loop trough the values (g_f42 holds the value of the property)*/     
     for i in 1 .. apex_application.g_f42.count loop
          /*g_f41 holds the key to the default property*/
          if apex_application.g_f41(i) is not null and
               apex_application.g_f41(i) > 0 then
               insert into measurment_prop
               ( measrument_id
               , defprop_id
               , wrd)
               values
               ( v_objmet_id
               , apex_application.g_f41(i)
               , apex_application.g_f42(i)
          end if;
     end loop;
end;After running this process, the application branches back to the page, clearing the cache and set some items I use for filtering an other report with their own values.
Both the process and the branche have a 'when button pressed' condition, where the same button is filled in. The branche fires on submit: after processing.
When I hit the button to save the data, I get an error: ORA-01403: no data found
In the debug info I can find there is encountered an unhandeled exception in the process, but I don't know what's going wrong...
I thought it could be something with the date field, I want to save, so I put it in a to_date() with the right format, but I still got the error...
I've also checked if the query which fetches the nextval of the sequence is correct, and it is, no typeing error in the sequence name, or something.
I'm using APEX 4.0.2

Changed some code of the javascript, it directed to the wrong item ID, now its correct

Answer 1

My problem is solved. The error occured when application item g_f41 was accessed, so my application couldn't find the data, the user putted in there. I now pasted this part of the sql, to the other apex_item field, so it became one field and now it works correctly:
select [...]
apex_item.hidden(41,defprop.id) ||
decode(proptyp.id,
                1, apex_item.text(p_idx=>42,p_value=>''||
                    decode(defprop.srt, 'CONSTANT', (select WRD
                                                                        from    measurement_prop
                                                                        where    defprop_ID = defprop.id
                                                                        AND        measurement_id IN
                                                                            (SELECT ID
                                                                            FROM measurement
                                                                            WHERE OBJ_ID = obj.id
                                                                            AND DAT IN
                                                                                (SELECT latest_date
                                                                                from object_instance
                                                                                WHERE ID = obj.id)))
[... etc ...]
