Is it possible to cancel/evict changes made to the current em when @End'ing a nested
Conversation?
Typically I have two methods save() and cancel() on my nested Conversation-Components on
save I do em.flush() but on cancel() I need to "rollback" any changes.
Currently I loop through all entities and do em.refresh() on them but this seems a awkward
- is there any better way to do this?
