thanks for the reply oscar... i miss it in the documentation :( i see the static methods Bind/Unbind on it but i thought that was old code left there for retrocompatibility.
i also suggest to remove it (or use obsoleteAttribute), becouse is strange that to use it i must change also the code sorry maulo, i think that was better this group when asking samething about the nhibernate code, the next time i will post in nhuser
