Information about Session

[phanhan]

Hello everybody.
So I have a live site and two sites on my local machine.

At civisprint I upgraded one of them (let's call it JohnFF2) to 4.4.

Then, on the other (let's call it JohnFF1), running 4.2 I experienced the following problem:

I'm querying the session to find my ID, then using that to get any relevant memberships. The function I'm using is:
 
$session = &CRM_Core_Session::singleton();
$contactID = $session->get('userID');

However, $session doesn't have a userID field, unless I masquerade as a different user, whereupon it mysteriously all works!

Any ideas?

1) Could doing the upgrade have broken some of my other settings somehow? (I doubt it, but worth asking).
2) How should I be getting my userID if not by this way?
3) Why is it working on the masquerade, and not on the not masquerade?

Thanks.

Is one Drupal login connected to a CiviCRM id (via the uf table say) and the other isn't?

(It's interesting to see my brand being used to ask questions about upgrades I've done historically...)

Which module/extension are you finding this in?

Is the ampersand necessary before CRM_Core_Session::singleton()? We don't have one when we get the logged-in cid that way.
