Refresh the drop down list after update the table

Question

I have tab with three pages in each page one data block. I have table with primary key of combination of the other tables foreign key. I am populating the combination of foreign key in dorp down list. In the when-new-form-instance trigger I populate the two lists, work fine. But if I add a new record in the other tables and I need this one to display in the list. I am trying to execute the same procedure which is populate the list
First time I get this error. FRM-41337. How can refresh the list to display the new record as well.
Thanks in advance

What you wanna do is to display the element entered in the List after you have added it manualy.
I think you must re-populate the Recordgroup
again.
The Procedure you used to populate the RecordGroup in the When-new-Form-Instance,
must include the statement:
DELETE_GROUP()
like This:
PROCEDURE Populate_The_List(list_id ITEM, sql_stat VARCHAR2) IS
group_id RecordGroup;
outcome NUMBER;
BEGIN
--Create temporary record group.
group_id := CREATE_GROUP_FROM_QUERY('List_Elements', sql_stat);
IF ID_NULL(group_id) THEN
MESSAGE('Record Group could not be created in Populate_the_List.');
RAISE FORM_TRIGGER_FAILURE;
END IF;
--Populate record group.
outcome := POPULATE_GROUP(group_id);
IF outcome <> 0 THEN
MESSAGE('Record Group could not be populated in Populate_the_List.');
RAISE FORM_TRIGGER_FAILURE;
END IF;
--Populate list item
POPULATE_LIST(list_id, group_id);
--Destroy the temporary record group to release resources
DELETE_GROUP(group_id);
EXCEPTION
WHEN OTHERS THEN
MESSAGE('Internal error occurred in Populate_the_List.');
RAISE FORM_TRIGGER_FAILURE;
END Populate_the_List;
SQL_STAT refers to the SQL statement used further to populate the List.
Hope this Helps
