[mod_python] sessions don't work

Hello!

I'm getting started to learn modpython. I have done everything as said in docs.


So, I can use apache and util, but when I'd tryed to use Session:
================================================
from mod_python import apache
from mod_python import util
from mod_python import Session

def handler(req):
        sess=Session.Session(req)
        req.content_type = "text/html"
        fk = util.FieldStorage(req)
        req.write("OK")
        return apache.OK
================================================



I get error:
================================================
Mod_python error: "PythonHandler new"

Traceback (most recent call last):

  File "/usr/local/lib/python2.3/site-packages/mod_python/apache.py", line 299, in HandlerDispatch
    result = object(req)

  File "/usr/local/www/billing/new/new.py", line 23, in handler
    req.content_type = "text/html"

AttributeError: 'module' object has no attribute 'BaseSession'
================================================




Temporally, I've solve this problem by adding <input name="id" type="hidden" value="%(id)s"> in every form on site. But it's not good solution.

Please, give me an advise how to solve this problem...

Thank you,
