Hi, I have a question about populating auto generated id before transaction commit . We are using ... 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

Hi, I have one case where commit (update of entity in this case) is not taken in account unless database is actually closed and re-open, no error. I tried to use flush instead of close+re-open but it does not work. So currently there is a dirty close + open + reload on each update
