Automatic type generation - oracle

Question

I've created a function in a PL/SQL package that uses a custom type defined as table of numbers. I use an object of this type in an SQL query with the SELECT COLUMN_VALUE instruction like this :
The type definition in the package:
type T_IDS is table of my_table.col_id%type;
The query inside a procedure in the package body:
l_ids_list T_IDS ;
begin
select col_ids bulk collect into T_IDS from my_table;
select sum(t.rec_value) into total_value
from my_table t where t.col_id in (
select column_value from Table(l_ids_list) );
Everything works fine and when I compile this code, I can see a new type generated under my schema_name/type section.
Once I installed this on test environment, it fails the compilation with the errors :
Error: PLS-00642: local collection types not allowed in SQL statements
Error: PL/SQL: ORA-22905: cannot access rows from a non-nested table
item
Database versions (local and test) are exactly the same, 11g. Is there a way to activate such a generation on the DBMS?
exemple to reproduce :
create table my_table (
col_id number,
rec_value number
);
insert into my_table (col_id, rec_value) values (1,100);
insert into my_table (col_id, rec_value) values (2,200);
insert into my_table (col_id, rec_value) values (3,300);
insert into my_table (col_id, rec_value) values (4,400);
commit;
package creation :
create or replace package test_pck as
type T_IDS is table of my_table.col_id%type;
procedure test_list;
end test_pck;
/
create or replace
package body test_pck as
procedure test_list is
l_ids_list T_IDS ;
total_value number;
begin
select col_id bulk collect into l_ids_list from my_table;
select sum(t.rec_value) into total_value
from my_table t where t.col_id in (
select column_value from Table(l_ids_list) );
end test_list;
end test_pck;

what you are doing is wrong. you should be creating SQL types and not using pl/sql types to access the TABLE function.
now as to WHY it actually sorta worked in your Dev env.
The silent pl/sql table creation is intended for pipelined functions and has been around for a while, but you're using this in a non-pipelined function and as such THIS SHOULD FAIL. In 11g release 1 (11.1.0.7 to be precise) though, a bug means that it actually compiles. If you actually tried to run it though you would get an error:
SQL> create package body foo
2 as
3
4 procedure test
5 is
6 l_ids_list T_IDS ;
7 total_value number;
8 begin
9 select col_id bulk collect into l_ids_list from my_table;
10 select sum(t.rec_value) into total_value
11 from my_table t
12 where t.col_id in (select column_value from Table(l_ids_list));
13 end;
14 end;
15 /
Package body created.
SQL> exec foo.test;
BEGIN foo.test; END;

now, Oracle FIXED this buggy behaviour in 11.2.0.3. now the error is thrown at compile time:

5 is
6 l_ids_list T_IDS ;

8 begin

in short, create an SQL type with create type and use that instead:
SQL> create type T_IDS as table of number;
2 /
Type created.
SQL> create package body foo
2 as

4 procedure test
5 is

10 select sum(t.rec_value) into total_value
11 from my_table t
12 where t.col_id in (select column_value from Table(l_ids_list));
