Hello.

I've just ported to the lates nhibernate version from 0.7.

It seems problem with empty strings and oracle is back. When I try to save field with empty string it says thay there is no length specified for parameter :p0.

I have to add extra code to interceptor and session proxy to convert all empty string to nulls. Is there a better solution?

You can try using EmptyStringType from NHibernateContrib, it should do the conversion for you.

Great. Thanks.

What about passing empty string as parameter like

return session.Find("...", new object[] {""}, new IType[] { ?????? });

EmptyStringType is IUserType. I can't use it here. Is there something I can use here?

I think you can just pass NHibernateUtil.String to Find in this case. Or use NHibernateUtil.Custom(typeof(EmptyStringType)).
