There is no problem to reference to session data managers. I have two
called userSession and siteSession and I set them one after another:

<dtml-var "REQUEST.set('uData', userSession.getSessionData())">
<dtml-var "REQUEST.set('sData', siteSession.getSessionData())">

However, I kinda find this funcitonality a bit useless since the two
objects are not all that independent. All it allows (since you are not
allowed yet to have two session_id_mgr) is to set different varialbes
with different timeout values. Can be usefull, but not truly persistant
where you want it to be. For instance, a simple session cookie that has
only the userid would be nice to keep forever, whereas the rest of the
session data expires with the browser session. Not currently possible.

Don't know if this helps....

Hi,
thanks for hammering it out.
The problems persit on my Site(2.3.3) under Win2k and OSX.
CST 0.8 works fine.
You tried to use 2 session Manager in 1 Transaktion simultaneously ?
perhaps
in 1 method ?
