Object Type Problem

Question

Hi
I faced some problems with O8(Release 8.0.5.0.0) object types.
Look at the following definition:
CREATE TYPE T_JMJX AS OBJECT( LBNO NUMBER(3),...);
CREATE TYPE LIST_JMJX AS TABLE of T_JMJX;
CREATE TABLE JXGC.JMJXJL
(JMJX LIST_JMJX,...)
NESTED TABLE JMJX STORE AS N_JMJXJL;
One day when I opened Schema Manager,I got a shock: TABLE JXGC.JMJXJL
has four colunms with the same name !!
name     schema datatype
JMJX     none LIST_JMJX
JMJX     none LIST_JMJX
JMJX     none LIST_JMJX
JMJX     JXGC LIST_JMJX
And I query USER_TAB_COLUMNS, it do have 4 records.
But in SQL*Plus I type 'decs JMJXJL',the column JMJX appears only once.
Other tables that has object type columns face the same problem.
This doesn't has any infection on my applications.
The real problem comes when one day I want to move the user JXGC to an
other server.
Export was done successfully but has a curious phenomenon:
Exporting NJMJXJL(the Nested Table)......19678 Exported
The number of rows Exported is about four times than the rows it
should has.
When Impport goes to the tables that have object type columns ,I got
the following errors:
Importing Table JMJXJL ........
IMP-00009: abnormal end of export file
Import terminated successfully with warnings.
Please help me to solve this problem.Thanks a lot!

Stone,
You need to go to metalink.oracle.com to file an iTAR on this.
