It looks like we will end up having a 2.0.3 release. I would prefer
not to put this fix for which there is an easy workaround into this
release especially as I don't think this fix is correct (we shouldn't
call setManualFlushMode() from there at all).

The main issue that I really want to see included in 2.0.2.SP1 is this
fix for the PersistenceProvider (JBSEAM-3030). It bothers me that we
are blatantly not supporting other JPA providers, even though we all
know how important manual flushing is (trust that I find it the single
most lacking feature in JPA). This is not a regression, but it sure
feels like one.
The backstory is that if you have at least one component with a
persistence context (e.g. @In private EntityManager entityManager or
@PersistenceContext private EntityManager entityManager), then Seam
will attempt to put it into manual flush mode before rendering. When
that happens, you are using the generic JPA provider, an exception is
thrown, failing the rendering process. The only way around this issue
is to implement your own PersistenceProvider and override the
setManualFlushMode() to do nothing. My fix changes this exception to a
log warning message.
