Populate list item dynamically

Question

Hi all.
I have a problem. I must populate a list item with a select, using the add_list_element statement inside a loop, using a cursor. My problem is that I must parametrize the select of the cursor: I pass a parameter in the procedure which is a field of the select of the cursor, but I have no result. The statement is the follow
cursor c1 is
select distinct("name of the parameter")
from table
order by 1;
When I execute this statement I have no result. Is there anyone to help me???
Thank you all for your collaboration.

Hi dear,
as for as i understood your problem, you want to populate the element list with a select query and your are using cursor and add_elements for this purpose which is complex and lenghtly,
why dont you use populate_group and populate_group_with_query built-ins instead of add_elements built in, by above mentioned two builts ins, you can populate the element list with a query and even you can refresh your element list at any time during runtime by populate_group_by_query. here is an example, you can also take benefit from forms builder help;
in new_form_instance trigger write following code to populate a list with select query;
DECLARE
rg_id RecordGroup;
errcode NUMBER;
BEGIN
rg_id := Create_Group_From_Query( 'LIST1_GRP','select code_name, code_no from any_table where code_name = ''0107''',FORM_SCOPE,200);
errcode := Populate_Group( rg_id );
Clear_List('CNOTE_TYPE');
Populate_List('CNOTE_TYPE','ACCNO_GRP');
end;
user populat_group_by_query to refresh list elements after the forms is already load and elements list is already populated.
any further question, feel free.
