Using OFFLINE_INSTANTIATION with a spatial object - SDO_GEOMETRY type

Question

Hello
I am looking for guidance on the usage of DBMS_REPCAT_RGT.INSTANTIATE_OFFLINE for a table object with an SDO_GEOMETRY
column defined.
The table is:
SQL> descr jtx.jtx_jobs_aoi
Name Null? Type
OBJECTID NOT NULL NUMBER(38)
JOB_ID NUMBER(10)
SHAPE MDSYS.SDO_GEOMETRY
SE_ANNO_CAD_DATA BLOB
The mview is defined as:
CREATE MATERIALIZED VIEW jtx.JTX_JOBS_AOI REFRESH FAST WITH PRIMARY KEY FOR UPDATE AS
SELECT * FROM JTX.JTX_JOBS_AOI@ncgsdb_master_s;
And the command we are using is:
SQL> SET SERVEROUTPUT ON
SQL>
SQL> DECLARE
2 dt_num NUMBER;
3 BEGIN
4 dt_num := DBMS_REPCAT_RGT.INSTANTIATE_OFFLINE(
5 refresh_template_name => 'jtx_refg_dt',
6 user_name => 'jtx',
7 site_name => 'NCGSDB_MVSITE1',
8 next_date => SYSDATE,
9 interval => 'SYSDATE + (1/96)');
10 DBMS_OUTPUT.PUT_LINE('Template ID = ' || dt_num);
11 END;
12 /
When we run this on an 11.1.0.6 database we get:
DECLARE
ERROR at line 1:
ORA-30373: object data types are not supported in this context
ORA-06512: at "SYS.DBMS_REPCAT_RGT_CUST", line 1991
ORA-06512: at "SYS.DBMS_REPCAT_RGT", line 1330
ORA-06512: at line 4
Now the strange thing is this appears to work for ONLINE_INSTANTIATION.
1. Is this supported?
2. If so what are we doing wrong?
Thanks
Richard

Here a full example with  CAST MULTISET as @PhilHerring wrote and with CAST COLLECT using the simplest possible function make_geometry:
CREATE OR REPLACE TYPE t_sdo_geometries AS TABLE OF MDSYS.sdo_geometry;
CREATE OR REPLACE FUNCTION make_geometry (p_points t_sdo_geometries)
  RETURN t_sdo_geometries IS
BEGIN
  RETURN p_points;
END;
SELECT make_geometry (
        t_sdo_geometries (
          sdo_geometry(2001, 32774, sdo_point_type(1, 1, null), null, null),
          sdo_geometry(2001, 32774, sdo_point_type(2, 2, null), null, null),
          sdo_geometry(2001, 32774, sdo_point_type(3, 3, null), null, null),
          sdo_geometry(2001, 32774, sdo_point_type(4, 4, null), null, null)))
        AS geom
  FROM DUAL;
WITH geoms(pcol) AS
(SELECT sdo_geometry(2001, 32774, sdo_point_type(1, 1, null), null, null) FROM dual UNION ALL
  SELECT sdo_geometry(2001, 32774, sdo_point_type(2, 2, null), null, null) FROM dual UNION ALL
  SELECT sdo_geometry(2001, 32774, sdo_point_type(3, 3, null), null, null) FROM dual UNION ALL
  SELECT sdo_geometry(2001, 32774, sdo_point_type(4, 4, null), null, null) FROM dual)
SELECT make_geometry(cast(multiset(select pcol from geoms a) as t_sdo_geometries)) FROM dual;
WITH geoms(pcol) AS
(SELECT sdo_geometry(2001, 32774, sdo_point_type(1, 1, null), null, null) FROM dual UNION ALL
  SELECT sdo_geometry(2001, 32774, sdo_point_type(2, 2, null), null, null) FROM dual UNION ALL
  SELECT sdo_geometry(2001, 32774, sdo_point_type(3, 3, null), null, null) FROM dual UNION ALL
  SELECT sdo_geometry(2001, 32774, sdo_point_type(4, 4, null), null, null) FROM dual)
SELECT make_geometry(cast(collect(pcol) as t_sdo_geometries)) FROM geoms;
Hope that helps
