Tue Sep 4 18:30:33 EDT 2012

    [ https://issues.jboss.org/browse/JBSEAM-3857?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12715906#comment-12715906 ] 

Marek Novotny commented on JBSEAM-3857:
---------------------------------------

Looking at http://docs.jboss.org/hibernate/orm/4.1/manual/en-US/html_single/#objectstate-flushing, there is explicitly written that FlushModeType.Manual is Hibernate extension to JPA and therefore it is ignored if you use SFSB as specification knows only AUTO and COMMIT modes.

I will add this into Seam reference documentation as a warning.
