Frm - 41337 - can not populate the list from record group

Question

Hi
I have created a form with 4 combo boxes. And i am trying to populate the 4 combo boxes dynamically.
Here is my table structure.
BUS_FUNCTION VARCHAR2(500),
SEQ NUMBER,
STEP1 VARCHAR2(500),
STEP2 VARCHAR2(500),
STEP3 VARCHAR2(500),
STEP4 VARCHAR2(500),
KEYSTEP VARCHAR2(4000),
OBJ_NAME VARCHAR2(500),
SME VARCHAR2(50)
In the fist combo box i am retriving bus_function and second seq and third step1.
i wrote a trigger when_new_form_instance and i am calling a procedure from the trigger.
here is my procedure code.
PROCEDURE fp_get_list IS
l_sql_text VARCHAR2(2000);
BEGIN
l_sql_text := 'SELECT bus_function,bus_function FROM TABS_BUS_FUNC';
lp_populate_list('BUSFUNC.list22','rgcat2',l_sql_text);
l_sql_text := 'SELECT TO_CHAR(SEQ),TO_CHAR(SEQ) FROM TABS_BUS_FUNC';
lp_populate_list('BUSFUNC.BUS_FUNC','rgcat',l_sql_text);
l_sql_text := 'SELECT step1,step1 FROM TABS_BUS_FUNC';
lp_populate_list('BUSFUNC.list20','rgcat1',l_sql_text);
END;
Now the problem is i can able to get the values fro the first two colums. but the third column values are not populating.
i am getting an error frm - 41337 - can not populate the list from record group.
PLease help me in this.
Thanks in advance,
Raju

Answer 1

I got answer
i write a code in when-new-form-instance
declare
v_rg_id RECORDGROUP;
v_return number;
v_query varchar2(2000);
outcome number ;
begin
v_rg_id := CREATE_GROUP_FROM_QUERY('RG_LIST','select Dname,To_char(Deptno) deptno from dept');
v_return := POPULATE_GROUP(v_rg_id);
POPULATE_LIST('emp.deptno', 'RG_LIST');
end;
but remember property of list item must be mapping of others value null and initial value null
