I'm using iBatis DataMapper 1.6.2, iBatis DataAccess 1.9.2 and Informix .NET Provider 2.81 included in Informix Client SDK 2.90.

When I use the configuration existing in providers.config for Informix .NET Provider, an exception is thrown calling the method daoManagerBuilder.Configure(".//Configuracion//iBatis//dao.config").

The exception is an "Object reference not set to an instance of an object" and it is thrown into CreateConnection() method of class DbProvider, in the call (IDbConnection)((ICloneable)_templateConnection).Clone();

I found that IfxConnection is ICloneable, but if the connection is not open a call to Clone() method throws the exception.
