How to dynamically change ACL of a logged in user? - Joomla! Forum - community, help and support

we've written plugin adds registered users new group called "customers" using below code. problem have log out , in again see menu items, etc. associated customers. i've tried number of variations of these functions (not in order shown) make joomla recognize them new acl, no luck.

code: select all

            $user = jfactory::getuser();
            juserhelper::addusertogroup($user->id, 9);  //make user customer
            $user_new = new juser($user->id);
            $user_new->getauthorisedgroups();
            $user_new->getauthorisedviewlevels();
            $session = jfactory::getsession();
            $session->set('user', $user_new);


there way accomplish this? between iterations , protected objects, can't seem find way it.

in case it's not clear, want "registered" user become "customer" (this part works), , immediately have acl needed see menu items visible "customers" without having log out, , in again.

i'm pretty new php , joomla! , know if there way make joomla! 2.5 recognize change in acl without user logging out , logging in.

the changes in acl @ site have don't take affect until logout/login complete, though there code included regarding refreshing sessions , updating database.

any appreciated!
