I am populating the list item from predefined record group. the form is running fine but it didnt show the data present in the record group. I have placed the following code in Pre-Form trigger.

declare
list_id item;
rg_id recordgroup;

begin

rg_id := find_group('RECORD_GROUP9');

list_id := find_item('block2.list4');
clear_list(list_id);
populate_list(list_id, rg_id);

end;

There's nothing obviously wrong with the code so I'd assume the record group contains no records.

anyways i have solved my problem by getting the things other way around. he is the general code and every one can use it by passing the name of the item and query as argument to this function

PROCEDURE fill_list (v_item varchar2, v_query varchar2) IS

rg_id RecordGroup;
list_id Item;
error number;

BEGIN

rg_id := find_group ('Test');
if ID_Null (rg_id) then
rg_id := create_group_from_query ('Test', v_query);
end if;
error := populate_group(rg_id);
list_id := Find_Item (v_item);
clear_list (list_id);
populate_list (list_id, rg_id);

END;

but if still someone find the error in the previous it will be appreciated Smile

About your previous issue,

In your query

Try to make the first column as ELEMENT which is the display of your list, and second column as value,

Don't forget to check data type and maximum length of list item
