This is old news to most people I guess. But I’m currently working with a legacy database where I can’t just go and do a “alter table” statement and introduce “@hibernate.version” or something to get saveOrUpdate() to work in the session.

Currently all operations created an insert…

So this is what I finally read on the topic(7.4. Components as composite identifiers):

You may instead implement Interceptor.isUnsaved() if you wish to use saveOrUpdate() or cascading save / update. As an alternative, you may also set the unsaved-value attribute on a (or ) element to specify a value that indicates a new transient instance. In this case, the version of the entity is used instead of the (assigned) identifier and you don’t have to implement Interceptor.isUnsaved() yourself.

So! A slight change in the persistance layer, and I think I’ll be fine
