SqlException -E.Library-TableValueFunctions

Hi!

I'm using VS2005, C#, Enterprise Libraries 3.1, SQL Server Express 2005. When i try to execute a TableValueFunction (with one parameter "idCliente") the SQL server trows a SQL Exception -Error to request stored procedure. 'DameProcesosClienteId' is a TableValueFuntion-.

Does anybody the same problem and knows how to fix it?

I think is not a rights problem in Server because 'user' have a 'sysadmin' rights.

Thank you for you help!

[C# code]

Database db = DatabaseFactory.CreateDatabase();
DbCommand dbCommand = db.GetStoredProcCommand("DameProcesosClienteId");
db.AddInParameter(dbCommand, "idCliente", DbType.Int32, 4);
db.AddInParameter(dbCommand, "idCliente", DbType.String, 4); //i tried both

using (IDataReader dataReader = db.ExecuteReader(dbCommand)) //HERE!!!
{
    while (dataReader.Read())
        {
        Console.WriteLine(dataReader["Dato"]);
    }
}
