Populating entity id before transaction commit

Hi, I have a question about populating auto generated id before transaction commit. We are using OBD with Spring and transactions are managed by Spring. The problem is, that we have custom annotation that wraps some of those functions to do additional work. But this annotation is executed before transaction is committed so all returned entities are not populated with ID in this context. How can I force ODB to populate entity ID before transaction is committed? Or maybe there is another way to finding ID of entity before commit? #1 2013-01-25 20:11 Hi, I have a question about populating auto generated id before transaction commit.

ODB should auto-restart if it detects it's necessary

Hi! I find very tricky the need to restart ObjectDB server after schema modifications in a distributed environment. Moreover, not doing it does sometimes trigger ugly errors, which mean application downtime. It might be very useful to have an additional feature (that could be enabled/disabled in objectdb.config) that each time ObjectDB detects a schema change that requires restart, it should automatically restart itself. This way we save a lot of headaches from our dev. ops. Currently we have to manually do: #1 2014-03-29 08:33 Hi!
