Subject: 7.3 "group by" issue

Hi folks,
This query:
SELECT element_id as wle_element_id, COUNT(watch_list_id)
FROM watch_list JOIN watch_list_element
ON watch_list.id = watch_list_element.watch_list_id
AND watch_list.user_id = 1
GROUP BY watch_list_element.element_id
gives this error:
ERROR: Attribute unnamed_join.element_id must be GROUPed or used in
an aggregate function
Note that in the select the table name is not mentioned but it is in
the GROUP BY. To solve the problem, you either have to name the
table in both locations or not name it in either location.
Why?
