Create stored outline failed...Any idea?

Create or replace stored outline on ...

Failed with the error below.  Any way to get around this issue so that an outline can be created for this Oracle Applications seeded SQL?

Thanks.

SQL> @create_stored_outline
            FROM TABLE (CAST (:b1 AS jtf_varchar2_table_2000))) res,
