[jboss-user] [JBoss Seam] - Re: Nested conversations and transaction management

OK, I really have no idea what you are doing, your code does not match your description. Stop using stuff like nested conversations until you have the basics working. anonymous wrote : | a) Is the database transaction started when the conversation starts, committed when the conversation is ended (@End) and rolled back if the conversation is rolled back (@Rollback) ? | This should be true, since if I call a.cancel() from the A page, the database is not changed | No, this is not true. Read my first two replies: if you use TransactionalSeamPhaseListener your conversation demarcation does not influence transactions in any way. It does not matter that there is a long-running conversation. A JSF requests is wrapped in a system transaction (in two transactions, in fact). @Rollback does a rollback of the transaction, again, not related to conversations. anonymous wrote : | b) When a nested conversation is started, the database transaction is nested ? | If not so (a new database transaction is started) when the nested transaction is closed, the database transaction is committed and there is no way to have changes undone | There are no nested transactions in Java EE.
