Create view on type??

Question

Hi all,
Yesterday, I hit the bug:
DataPump Export (expdp) Returns ORA-1427 When Partitioned IOT With Same Name Exists in More Than One Schema [ID 1064840.1]
One of the resolutions for this is to re-create ku$_iotpart_data_view view with the following code:
create or replace force view ku$_iotpart_data_view of ku$_table_data_t with object OID(obj_num) as
select '1','2',
       ip.obj#,
       (select o1.obj#
        from   obj$ o1
        where  o1.name=bo.name
               and o1.subname=o.subname
               and o1.owner#=o.owner_num),
       o.subname,
       NULL,
       po.parttype,
       t.property,
       t.trigflag,
       dbms_metadata_util.get_xmltype_fmts(t.obj#),
       decode ((select 1
                from   dual
                where  (exists (select q.obj#
                                from   sys.opqtype$ q
                                where  q.obj#=t.obj#
                                       and q.type=1 /* xmltype col */
                                       and bitand(q.flags,2+64)!=0))), /* CSX or SB */
                1,'Y','N'),
       decode ((select count(*) /* outofline xml table */
                from   sys.opqtype$ q
                where  q.obj# = t.obj# and
                       bitand(q.flags, 32) = 32 ),
                1,'Y','N'),
       'N', /* partitioned table cannot have column with LONG datatype */
       decode ((select count(*)
                from   sys.type$ ty, sys.coltype$ ct
                where  ty.toid=ct.toid and ty.version#=ct.version#
                       and ct.obj#=t.obj#
                       /* 0x00008000 = 32768 = contains varray attribute */
                       /* 0x00100000 = 1048576 = has embedded non final type */
                       and bitand(ty.properties,1081344)=1081344),
                0,'N','Y'),
       decode ((select count(*)
                from   sys.refcon$ rf, sys.col$ c
                where  c.obj#=rf.obj# and c.intcol#=rf.intcol#
                       and c.obj#=t.obj#
                       and bitand(rf.reftyp,1)=0), /* ref is non-scoped */
                0,'N','Y'),
       'N', /* default 'has_tstz_cols' to 'N' */
       value(o),
       ts.name, ts.blocksize, b.bytes_alloc,
       value(bo),
       -- if this is a secondary table, get domidx obj and ancestor obj
       decode (bitand (bo.flags, 16), 16,
               (select value(oo)
                from   ku$_schemaobj_view oo, secobj$ s
                where  bo.obj_num=s.secobj#
                       and oo.obj_num=s.obj#
                       and rownum < 2),
               null),
       decode (bitand (bo.flags, 16), 16,
               (select value(oo)
                from   ku$_schemaobj_view oo, ind$ i, secobj$ s
                where  bo.obj_num=s.secobj#
                       and i.obj#=s.obj#
                       and oo.obj_num=i.bo#
                       and rownum < 2),
               null),
       um.unload_method,
       um.et_parallel,
       (select count(*)
        from   rls$ r
        where  r.obj#=t.obj# and r.enable_flag=1 and bitand(r.stmt_type,1)=1),
        0 -- note: piot cannot be ref partitioned
from   ku$_iotpart_bytes_alloc_view b,
       ku$_schemaobj_view o, ku$_schemaobjnum_view bo,
       ku$_unload_method_view um, tab$ t,
       ind$ i, indpart$ ip, ts$ ts, partobj$ po
where  ip.obj# = o.obj_num
       AND o.type_num = 20 -- index partition
       AND bo.obj_num = po.obj#
       AND ip.bo#=i.obj#
       AND i.type#=4 -- iot index
       AND i.bo#=t.obj#
       AND t.obj# = um.obj_num
       AND ip.ts# = ts.ts#
       AND b.obj_num=ip.obj#
       AND bo.obj_num=i.bo#
       AND (bitand (bo.flags,16)!=16
            OR sys.dbms_metadata.oktoexp_2ndary_table(bo.obj_num)=1)
       AND (SYS_CONTEXT ('USERENV','CURRENT_USERID') IN (o.owner_num, 0) OR
            EXISTS (SELECT *
                    FROM   sys.session_roles
                    WHERE  role='SELECT_CATALOG_ROLE'))
/I did that as sys and created in INVALID state. When i do show errors, I get "table or view does not exist".. and indeed, if i search the object on what this view is being created, i get the following:
sys@devbase> select object_name, object_type, status
2 from dba_objects where object_name like '%TABLE_DATA_T%';
OBJECT_NAME OBJECT_TYPE STATUS
KU$_TABLE_DATA_T TYPE VALID
This is an Oracle Type. I am not sure if we can create views on types... And even if can, why am I getting ORA-00942 if i am connected as sys???
Did anybody hit this problem? Can you please help to compile this thing?
Thanks a lot in advance!!!

Thanks for formatting the original post. It now makes a lot more sense.
Still worth opening a SR even though it's non-critical. Nothing wrong with asking both places - especially since you know that it'll take days before they get to it, so why wait those days AFTER you give up here <g>
As to your question whether views can be created on types, reference the SQL Language Reference manual at http://download.oracle.com/docs/cd/E11882_01/server.112/e17118/statements_8004.htm#i2065510 where it states
Use the CREATE VIEW statement to define a view, which is a logical table based on one or more tables or views. A view contains no data itself. The tables upon which a view is based are called base tables.
You can also create an object view or a relational view that supports LOBs, object types, REF data types, nested table, or varray types on top of the existing view mechanism. An object view is a view of a user-defined type, where each row contains objects, each object with a unique object identifier.
I would encourage you to post the actual error message from the compile.
