[JBoss JIRA] (CDI-705) BEFORE_COMPLETION Transactional observer is notified for transaction which is marked for rollback

[ https://issues.jboss.org/browse/CDI-705?page=com.atlassian.jira.plugin.sy... ] Ondra Chaloupka edited comment on CDI-705 at 6/6/17 9:22 AM: ------------------------------------------------------------- Tom already mentioned it so these are just my two cents: as I understand it, the main difference is in the fact that {{beforeCompletion}} is expected to be called with the active transaction context (by spec it's required). That provides the way for e.g. JPA (as Tom mentioned) to call flushes etc. That's are operations which are needed for data changes being made visible for the consumer - that's when the transaction *is going* to be committed. When the transaction *is not going* to be committed (was rolled back or marked to roll back) then first there is no need for such operations (and they could be considered as superfluous). Plus at that time the transaction context could not be available (as txn could be rolled back) and operations working on beforeCompletion context is expecting to use it. The {{afterCompletion}} is expected to be called without active transaction context - that's true for commit and rollback. For both cases, the transaction already finished and there isn't any notion of it. From that point, both cases are the same. was (Author: ochaloup): Tom already mentioned it so these are just my two cents: as I understand it, the main difference is in the fact that {{beforeCompletion}} is expected to be called with the active transaction context (by spec it's required).
