Error ORA-21525 procedure with a type object parameter

Question

Hi.
I have some types in DB :
CREATE OR REPLACE TYPE tListaValori IS TABLE OF VARCHAR2(4000);
CREATE OR REPLACE TYPE TFILTRO AS OBJECT
TIPOFILTRO VARCHAR2(200) ,
VALORI tListaValori ,
NULLVALUE VARCHAR2(4000)
CREATE OR REPLACE TYPE tListaFiltri IS TABLE OF TFILTRO ;
CREATE OR REPLACE TYPE TQBE AS OBJECT
ALIASTAB VARCHAR2(30),
COLONNA VARCHAR2(30),
SELEZIONE VARCHAR2(3),
TIPODATO VARCHAR2(30),
ORDINAMENTO INTEGER, -- VEDI BINARY_INTEGER
TIPOREL VARCHAR2(6),
Filtri tListaFiltri,
AliasNew VARCHAR2(30),
Raggruppa INTEGER -- VEDI BINARY_INTEGER
So I create C# classes by the wizard of visual studio 2005 that map UDTs to c# classes.
In compilation there aren't errors but when I call the procedure (from the main method in visual studio) :
procedure UPDATE_OGGETTO(
param1 IN OUT TQBE
as
begin
NULL;
EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE(SQLERRM(SQLCODE));
end;
I have the following error:
Eccezione non gestita: Oracle.DataAccess.Client.OracleException ORA-21525: il numero dell'attributo o (elemento di collection all'indice) %s ha violato i suoi vincoli in Oracle.DataAccess.Client.OracleException.HandleErrorHelper(Int32 errCode, OracleConnection conn, IntPtr opsErrCtx, OpoSqlValCtx* pOpoSqlValCtx, Obj
ect src, String procedure)
