Fabio Massimo Ercoli I think this should be covered by your work on HSEARCH-3360 Resolved , but the nested transaction thing makes me doubt. In particular, I wonder what happens in this scenario:

• open transaction A
• change entities without flushing
• open nested transaction B
• change entities
• flush
• rollback transaction B (should clear the session?)
• back to transaction A
• flush
• commit

This may not be a valid use of nested transactions, I don't know. I'm mainly wondering what will happen to the changes performed in transaction A...
