Can't open a object view with mapinfo

Question

i have created this object view (with toad 7.6 in a server oracle 9i ITA, i use mapinfo 7.5 ITA):
CREATE OR REPLACE FORCE VIEW PRG.VISTAMORD
(PIANO_STORIA_ID, ANAGR_ID, PIANO_ID, TIPOMOD_COD, ZTO,
PRG, PIANO_STATO, ATTO_DATA, ATTO_TIPO, ATTO_NUM,
PIANO_VARIANTE, PIANO_NOME, PIANO_NOTE, PIANO_POS_ARCH, PIANO_LEGGE,
ANAGR_COD_COM, MI_STYLE, MI_PRINX, GEOLOC, ST)
AS
SELECT a.Piano_storia_id, a.Anagr_id, a.Piano_id, a.tipomod_cod,
a.ZTO, a.PRG, b.piano_stato, b.atto_data, b.atto_tipo, b.atto_num,
     b.piano_variante, b.piano_nome, b.piano_note,
     b.piano_pos_arch, b.piano_legge, c.anagr_cod_com,
     d.mi_style, d.mi_prinx, d.geoloc, d.st
from (piano b inner join ((oggetti_storia a
inner join aux_indice e on (a.piano_storia_id=e.piano_storia_id)
          and (a.anagr_id=e.anagr_id) and
(a.piano_id=e.piano_id)) inner join anagrafica c on a.anagr_id = c.anagr_id)
     on b.piano_id = a.piano_storia_id) inner join oggetti_spazial d
          on a.anagr_id = d.anagr_id
where ((a.tipomod_cod)<>'DEL')
order by piano_storia_id;
where oggetti_spazial is a object table (a mapinfo map imported in Oracle)
if i don't add the order by clause the view is ok and i can open it in mapinfo,
with the order by clause, when i try to open the view mapinfo give the error:
"errore Oracle: ORA-00600: codice errore INT., argom.:[15819],[5582],[],[],[],[],[],[]. Impossibile recuperare i record nella tavola.
can You Help me?

Hi Gabriel,
I think with enough patience one could get the ASCII DataPlugin Wizard to create a DataPlugin that would work for your file, but the resulting code generated by the wizard is not easily understandable, and it would not have correctly devined the sampling rate from your file format.  I've written a DataPlugin from scratch which correctly reads the data snippet you sent over.  I included an implicit time channel so that you could easily see the time values inferred from the "SampleRate" line.  The implicit time channel rerquires all the lines in the ASCII file to be parsed in order to figure out the correct channel length (line 58), so if you have large data files you should comment out the time channel lines (44, 45, 58) and use just the implict time information already encoded in the data channel waveform properties (for faster file indexing).  Unless your files are verry large, though, I think you'll like the DataPlugin as it is.
