Using PIPELINED in VO

Question

Hello,
I have 2 types:
create or replace type e1e2 AS OBJECT (
e1 varchar2(3),
e2 varchar2(3));
CREATE OR REPLACE TYPE e1e2_tabtype AS TABLE OF e1e2;
and function:
CREATE OR REPLACE function manage_type(ee in varchar2) return e1e2_tabtype PIPELINED
as
e1 varchar2(3);
e2 varchar2(3);
CURSOR e IS
SELECT 'o' one, ee two from dual
union
SELECT ee one, 'o1' two from dual;
begin
open e;
loop
fetch e into e1,e2;
EXIT WHEN e%NOTFOUND;
PIPE ROW (e1e2 (e1,e2));
end loop;
close e;
return ;
end manage_type;
and query:
select e2,e1 from TABLE (manage_type(:P))
the query returns 2 rows in TOAD, but when I create a view object on the query it raise error:
SELECT * from (select e1,e2 from TABLE(manage_type(:P))) QRSLT where 1=2 - ORA-22905: cannot access rows from non-nested table item.
The same query works fine without parametrs:
lselect * from TABLE(mamage_sergey_type('0')) ---- works!
I wonder why legal query does not work in view object. I have not seen any restrictions on using TABLE function in ADF.
I need it to work against Oracle 8i.

SNikforov,
Try this query for your VO:
select e1, e2 from table(cast (manage_type(:P) as e1e2_tabtype))ADF will wrap your VO query (as you can see) with "select * from (<your query here>) qrslt where 1=2 - if your query works fine with SQL*Plus in that fashion, it should work with ADF.
