Hi.

My problem is that hibernate tries to update object which is previously selected from the db and the object has not changed during the transaction. The point is that the connected user has no update grants ot that table which throws an exception each time hibernate tries to update the persistent object. Is there any way to tell the hibernate not to update the object?

Greetings

Enable logging at DEBUG level and search for "is dirty", you should then see what properties NH considers dirty.

To prevent NH from ever updating an object, use mutable="false" in <class>.

I've got the same problem.
I've found the line with the "dirty" information.

What does it mean that NHibernate considers a property of my object "dirty" ?
Thanks

Dirty means that the state of the object in memory is different then in the database and Hibernate knows about it and intends to fix this on the next batch update.

A new object is immediately dirty since it's id is not set.
A persistent object is dirty if it has been changed.
