Can Castle ActiveRecord do optimistic locking on properties? I found optimistic locking for the entire class, but not for an individual property. In my case, I need to make it so that adding/removing elements in a collection does not update the version number of the entity (so for example, adding a Product to a Store without changing any of Store's properties will not increment the version number).

A:
NHibernate supports an optimistic-lock property that can be applied to properties or collections and does exactly what you want when set to false (default is true)
I think ActiveRecord doesn't currently expose it. Not sure how hard it would be to extend it.

Thanks. That's pretty disheartening to hear.

Well, being open source, it's just a matter of downloading the sources and checking where the mappings are generated. Moving to non-wrapped NHibernate is the next alternative.

To confirm Diego's answer: ActiveRecord doesn't currently support the optimistic-lock attribute on properties/collections. It's not hard to implement though, see http://github.com/castleproject/Castle.ActiveRecord/blob/master/src/Castle.ActiveRecord/Framework/Internal/Visitors/XmlGenerationVisitor.cs#L598
