This happens on the development server, using JPA. In the request
there are:
1. transaction.begin; run query; transaction.commit; log
(transaction.isActive)
2. (w/o transaction) delete entry; log(transaction.isActive)
3. (w/o transaction) add entry; log(transaction.isActive)
4. (w/o transaction) add entry; log(transaction.isActive)
5. log(transaction.isActive); close connection (i.e. close
entityManager)
And "close connection" fails, because it tries to commit a
transaction, which fails because there are two entities in different
entity groups - see the messages bellow. And at any point the logs
show "transaction.isActive::false".
My question - why at "close connection" does it try to commit, if
there is no active transaction??
