Subject: Re: a calculator portlet
Hello Ruben,
thanks for your response, i ve solved the problem by myself. it was not a
failure of a role, because i've created a special role for this portal side
an the "user" called "dieter developer" :) was in this role. the problem
i've had was a problem with the session attributes i've had there a bug.
