MySQL, Stored procedures with parameters and @ signs, upgrading to 2.1

Having just upgraded to 2.1 and run subcommander I found that all the methods in StoredProcedures.cs that use parameters have parameter names that are wrong.

They read :    

            sp.Command.AddParameter("?@_startPage", StartPage, DbType.Int32, null, null);

When they should read :

            sp.Command.AddParameter("?_startPage", StartPage, DbType.Int32, null, null);
         
 Where's the extra @ sign come from??

 The problem seems to be with the MYSQLDataProvider.cs

As a quick fix I changed

GetSPParams in  MYSQLDataProvider.cs to read like so :

   if (param.ParameterName.StartsWith("@"))
                    {
                        row[0] = param.ParameterName.Substring(1);
                    }
                    else {
                        row[0] = param.ParameterName;
                    }

Not pretty, but it works.

So am I doing something else wrong to cause the additional @ sign ? Is it a problem with my procedures? Just wondered if anybody has a better idea than me. This wasn't the case with SubSonic 2.0.3. Thanks in advance for any comments.
