As EntityTransaction doesn't support 2-phase commit, you can have a corrupt state in case of failures when doing a multi-unit commit. Here is for example what Seam doc says: ------------ You should avoid EntityTransaction if you have more than one persistence unit in your application. Seam does not support installing multiple EntityTransaction beans, and the EntityTransaction interface does not support two phase commit, so unless you are careful you may have data consistency issues. If you need multiple persistence units in your application then we highly recommend using an EE 6 compatible server, such as Jboss 6. ------------- So may be we should forbid multi-unit commits in the same request? If @CommitAfter is placed and there are more than one active transactions, we can throw an exception.
