I think Andrey wants to do the opposite (??) - detect "phantom" changes that transfer an object to the MODIFIED state, but do not result in a DB record update.

Well, the Artist object didn't really change.  Could you override
Artist's addToPaintings() (don't forget to call super) and record
somewhere that a change has been made?

Imagine you have Artist and Painting entities. You create a new Paining and attach it to existing Artist, then commit. The Artist object is marked as
modified, so LifecycleListeners will fire for it, but in fact nothing
changed in DB table (ARTIST). Is there any way to check if object has really changed? I suppose I could iterate through all attrs and simple to- one rels during lifecycle event, and compare values with cached snapshot of the CDO,
but this seems to be an ugly way..

Thanks,
