Why do i get ORA-03113 when doing a spatial query against union all view?

Question

Hi, i created the following view
CREATE OR REPLACE FORCE VIEW cola_markets_v
AS
  (SELECT mkt_id, NAME, shape shape_a, NULL shape_b, NULL shape_c,
          NULL shape_d
     FROM COLA_MARKETS
    WHERE NAME = 'cola_a')
   UNION ALL
  (SELECT mkt_id, NAME, NULL shape_a, shape shape_b, NULL shape_c,
          NULL shape_d
     FROM COLA_MARKETS
    WHERE NAME = 'cola_b')
   UNION ALL
  (SELECT mkt_id, NAME, NULL shape_a, NULL shape_b, shape shape_c,
          NULL shape_d
     FROM COLA_MARKETS
    WHERE NAME = 'cola_c')
   UNION ALL
  (SELECT mkt_id, NAME, NULL shape_a, NULL shape_b, NULL shape_c,
          shape shape_d
     FROM COLA_MARKETS
    WHERE NAME = 'cola_d');added the necessary entries in USER_SDO_GEOM_METADATA and created a spatial index on COLA_MARKETS (SHAPE). However, when i do a spatial query against this view, i get ORA-03113. A spatial query against the base table works fine. Any ideas why this happens? (This is Oracle 10.2.0.3.0)
Thanks in advance, Markus
PS: This is my spatial query
SELECT *
  FROM cola_markets_v t
WHERE sdo_filter (t.shape_a,
                         SDO_GEOMETRY (2003,
                                       NULL,
                                       NULL,
                                       sdo_elem_info_array (1, 1003, 3),
                                       sdo_ordinate_array (1, 1, 2, 2)
                         'querytype=window'
                        ) = 'TRUE';

Thank you for your reply. I have tried it with 11.1.0.6.0 today and it works. This might be an issue with 10.2.0.3.0.
