EJBQL: support paths across flattened relationships
---------------------------------------------------

                 Key: CAY-1069
                 URL: https://issues.apache.org/cayenne/browse/CAY-1069
             Project: Cayenne
          Issue Type: Task
          Components: Cayenne Core Library
    Affects Versions: 3.0
            Reporter: Andrus Adamchik
            Assignee: Andrus Adamchik
             Fix For: 3.0


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 = ?]
