Is there anyway to update the version of an entity without actually changing any of its data?

I have an instance where I need to manipulate some related objects to an entity but the entity doesn't hold a direct association to those objects in the mappings. When one of the related entities is updated, I want nhibernate to update the version of the main entity. Is this possible?

Long time ago, I had the inverse problem: I enabled cascading between two objects and whenever I saved the first, the version of the second was updated...

So you might enable cascading and see if you get the desired behaviour :wink:

Maybe I didnt set it up right but it didnt have the effect I was looking for. On a many to one assosciation, I set this mapping up:




This mapping did not cause the parent's version to get updated. Basically nothing ever happened to the parent on add, update, delete.

Any other ideas? Do I need another mapping on the other end? I'm trying to avoid the list mapping on the parent due to performance problems with collection mappings.

You can add the collection mapping and enable lazy loading; there will be no performance impact.
