change role dynamically ?

[cpage]

I,

i work with JBP 2.2.1RC1

i have a user with role admin and role1
i have a portlet "toto" with role "toto" in the main page.

the user add himself the role "toto" with the roleportlet or the userportlet.

i refresh the page/portal but the user don't see the portlet "toto".
i have to restart the server too see the portlet "toto"

is it normal ?
i was thinking that all was dynamic in JBP for the version i'm using ?


I seriously need to be able to dynamically change roles for the users (different context) without restart the server :p


thank you for help :)

sorry i forgot something.

i say that i need to restart server to see the changes apply but it's because the logout() don't work ! :p

what i need is to be able to changes roles and see the changes apply without logout.
