I'm slightly (sorry, that's irony ;-) concerned about this, it just seems wrong. System transactions are request scoped in Seam. Why do we need to do this?

In that case you need to disable Seam Managed Transactions (see the ref guide for more).

Note that the modification primarily addresses JBPAPP-3764 https://jira.jboss.org/browse/JBPAPP-3764 On 06/03/2010 06:08 PM, Denis Forveille wrote: > Hi, > > Recently, to address JIRA-4542 > (https://jira.jboss.org/browse/JBSEAM-4542) , the scope of the > EjbSynchronizations component has been changed from EVENT to SESSION. > > I'm worrying about the impact of such a change on the behavior on Seam > applications > > Is this change safe?

So, do you think this change is OK or do you think the change should be rollbacked (revert to the EVENT scope) and another solution should be investigated to solve JIRA-4542?

I had a short look. It looks to me like the problem occurs when Seam is invoked outside of the web lifecycle (e.g. by an MDB or custom request that calls Lifecycle.beginCall()/Lifecycle.endCall() or similar). Is that right - that this can't happen inside a regular SMT? If so, I think we will have to hack it for that case.
