EJB 3.0 does not support disabling automatic flushing of the persistence context. This was one of the questionable changes forced into the specification by certain experts.

As soon as other JPA providers also add this essential feature, Seam will support that too. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4039736#...
