Hi,

I think you just want something like:

(defc user nil)
(defc route "")

(defn role-of [user route]
    (when user
        (if (= "#/secret-route" route) :power-user :pawn)))

(defn get-submissions-for [user route]
    (when-let [role (role-of user route)]
        (get-submissions role (:email user))))

(cell= (get-submissions-for user route))

HTH,

Thanks, it worked.

I think the problem was that I was doing a refactoring and I was using (current-user) in some places instead of user. But current-user was defined as (defn current-user [] @user) which I guess broke javelin's dependency calculation.
