> Flattened relationships are not parsed properly by EJBQL yet. E.g.:
>   String ejbql = "SELECT f FROM FlattenedTest3 f, FlattenedTest1 ft "
>                 + "WHERE f MEMBER OF ft.ft3Array AND ft = :ft";
> SELECT t0.FT2_ID AS ec0_0, t0.NAME AS ec0_1, t0.FT3_ID AS ec0_2 
> FROM FLATTENED_TEST_3 t0, FLATTENED_TEST_1 t1 
> WHERE EXISTS (SELECT 1 FROM FLATTENED_TEST_3 t2 WHERE t2.FT1_ID = t1.FT1_ID AND t2.FT3_ID
= t0.FT3_ID) AND t1.FT1_ID = ? [bind: 1:1]
> 				
> 				java.sql.SQLException: Column not found: T2.FT1_ID in statement [SELECT t0.FT2_ID
AS ec0_0, t0.NAME AS ec0_1, t0.FT3_ID AS ec0_2 FROM FLATTENED_TEST_3 t0, FLATTENED_TEST_1
t1 WHERE EXISTS (SELECT 1 FROM FLATTENED_TEST_3 t2 WHERE t2.FT1_ID = t1.FT1_ID AND t2.FT3_ID
= t0.FT3_ID) AND t1.FT1_ID = ?]
