Ora-13226 when performing spatial query on view

Question

Hi,
in my database I have a view with spatial column. The view is based on UNION ALL select. When I try to run spatial query on the view, the database returns ora-13226 error. When I recreate the view to consist only one select (without UNION ALL) the spatial query return correct result. Could you pls help me how to do a spatial query on spatial view whose definition contains UNION ALL select?
Thanks
Andrew

Hi,
it's quite simple:
create view test_view as
select id, geometry from table_a
union all
select id, geometry from table_b;
When I try for example:
select *
from test_view
where sdo_relate(geometry, (select geometry from table_c where id=1316),'mask=anyinteract') = 'TRUE';
it throws ora-13226 error.
Interesting is that following query where the geometry is directly included runs well:
select *
from test_view
where sdo_relate(geometry, MDSYS.SDO_GEOMETRY (....),'mask=anyinteract') = 'TRUE';
also when I recreate the test_view as
create view test_view as
select id, geometry from table_a;
then also the first query (with inner select) returns no error.
It's a little bit strange isn't it?
