I think the simplest way to implement this (regardless of whether it's right thing or what reasons make you ask for it) is to map a nullable enum FIELD, and make a property (that is NOT mapped in NH), which reads and writes the field value. something like: * * *//Mapped in NH, nullable private Enu

Not sure about FNH, but using hbm mappings you don't need a setter if you declare a property with access="readonly". NH will keep track of the DB value, do dirty checks with it and issue the appropriate updates to the DB. Diego P.S. I'm writing this offline, sorry if somebody already answered

For my current project, we use a nHibernate session to retrieve the object, and another session to update the changes we've made to the object in between the two session. If we use SaveOrUpdate(), nHibernate will typically do a select-then-update (so, two calls to the database). However, our own b
