Analitical functions in recursive subquery factoring

Question

Hi,
I have a problem with analitical functions in recursive subquery factoring.
My version:

When I run following query it runs fine:
with a (num, total) as

  ,1 total

union all
select
  num + 1             num
  ,total + num + 1    total

The recursive member cannot contain any of the following elements:
- The DISTINCT keyword or a GROUP BY clause
- The model_clause
- An aggregate function. However, analytic functions are permitted in the select list.
- Subqueries that refer to query_name.
- Outer joins that refer to query_name as the right table.

According to this it should be posible to have an analitical function in here.
Also on this form I see samples of it used as such.
eg.:
Re: Seat Distribution-Can we do this in SQL?
Can anybody tell me if this is a problem with my version of oracle?
Or is there some other problem here?
Thanks,
