I have problems filling my list box in oracle forms.
I have made a program unit:
[SIZE=2]PROCEDURE vulpoplist
(v_recordgroep varchar2
,v_veldnaam varchar2)
IS
group_id recordgroup :=find_group(v_recordgroep);
list_id item:=find_item(v_veldnaam);
BEGIN
if populate_group(group_id)<>0 then
message('unabel');
raise form_trigger_failure;
end if;
clear_list(list_id);
populate_list(list_id,group_id);
END;[/SIZE]

And i have a trigger on form level
vulpoplist(list4,lov33);

list 4 is the list field and lov33 is my recordgroup

Now I get 2 errors:
Error populating group
Cannot find item : inavlid ID

Can anyone help me
