$user->get('gid') returns empty

[greno]

$user->get('gid') is returning empty under Joomla 1.6.

With the new ACL how should we be handling groups?

And specifically what replaces $user->get('gid')? I'm assuming it's something like putting all the groups into an array like:

Code: Select all

$getGroups = JAccess::getGroupsByUser($user->get('id'));

In the case of multiple groups which one would you select?
Which one was $user->get('gid') selecting previously?
