the Applicatin Admin of our system can no longer access this view
dba_role_privs since we upgraded from 10g to 11gR2.

this is what I have before:
-----
role (app_admin)
grant select on dba_role_privs to app_admin
grant app_admin to user -- applicatioin administrator
----

the above doesn't work anymore even after I recreated the whole
thing again.

Now, if I grant the user direct access to the view then it works fine.
grant select on dba_role_privs to user

any idea???

Thanks in advance
