-----------------------------------
Gavin suggested on the mailing list
(
http://lists.jboss.org/pipermail/seam-dev/2008-May/000282.html) that we introduce a
setRenderFlushMode() on PersistenceProvider. This method would instruct the
PersistenceContexts component what flush mode to use before the render response phase is
entered. The default implementation would not change the flush mode (no-op), whereas the
Hibernate implementation would set the flush mode to MANUAL.
If the application attempts to change the flush mode, for instance as a result of using
@Begin(flushMode = MANUAL) then a warning would be issued since Seam cannot perform the
request the application is requesting.
Don't be so hostile to alternate JPA providers when attempt is
made to use manual flush mode

Key: JBSEAM-3030
URL:
https://jira.jboss.org/jira/browse/JBSEAM-3030
Project: Seam
Issue Type: Bug
Components: Platform interoperability
Affects Versions: 2.0.2.GA, 2.0.3.CR1, 2.1.0.A1, 2.1.1.GA
Reporter: Dan Allen
Assignee: Dan Allen
Fix For: 2.0.3.CR2, 2.1.2.CR1, The future
Attachments: JBSEAM-3030-branch20-v1.txt, JBSEAM-3030-trunk-v1.txt,
NonHibernatePersistenceProvider.java
Original Estimate: 5 minutes
Remaining Estimate: 5 minutes
Right now, alternate JPA providers (such as TopLink) are *unusable* in Seam. This is
because, prior to the render response phase, Seam attempts to put the touched persistence
contexts into manual flush mode. This trickles down to a call to setManualFlushMode() on
the component returned by PersistenceProvider.instance(). The generic implementation
(PersistenceProvider) throws an exception when this method is called.
Throwing an exception here is overkill and hostile. I propose a log warning message,
which would allow the developer to tune the log settings to hush it, or if they really
don't like the log message, they can provide their own implementation. But at least
the damn thing will be usable.
