>Summary: JBoss-QL "IS NOT EMPTY" doesn't work
Initial Comment:
I'm running JBoss 3.0.1RC1 with Postgres 7.2.
The JBoss-QL "IS NOT EMPTY" statement doesn't work
it simply generates the SQL-statement "TRUE".
Sample:
JBoss-QL:
SELECT DISTINCT OBJECT(p) FROM Person p, IN
(p.nodePersonRoles) npr WHERE npr.node.tId LIKE ?1
AND p.cards IS NOT EMPTY
Generates SQL:
SELECT DISTINCT t0_p.person_id
FROM person t0_p, node_person_role t2_npr, card
t3_p_cards, node t1_npr_node
WHERE (t1_npr_node.t_id LIKE '1.' AND TRUE)
AND (t0_p.person_id=t3_p_cards.person_id
AND t2_npr.node_id=t1_npr_node.node_id
AND t0_p.person_id=t2_npr.person

TRUE is put there as a place holder to satify the where
clause. It gives the correct results for my simple tests.

I'm not sure why TRUE is there, but it also appends the join
clause "t0_p.person_id=t3_p_cards.person_id" which should do
the trick. Have you checked the results of the query to see
if they're correct?
