FlushModeType in Conversation

[nimo22]

When I use this:

@Begin (flushMode = FlushModeType.MANUAL )
public void call(Object o)
{
this.o= o;
log.info("entityManager.isOpen() #0", entityManager.isOpen());
log.info("entityManager.getFlushMode() #0", entityManager.getFlushMode());
}

then my console prints:

07:50:53,749 INFO  entityManager.isOpen() true
07:50:53,749 INFO  entityManager.getFlushMode() AUTO

Even the flushMode is set to Manual!?

When I use javax.persistence.FlushModeType instead of

import org.jboss.seam.annotations.FlushModeType and set the FlushMode-Type in the code:

entityManager.setFlushMode(FlushModeType.COMMIT);
log.info("entityManager.getFlushMode() #0", entityManager.getFlushMode());

then it prints

07:50:53,749 INFO  entityManager.isOpen() true
07:50:53,749 INFO  entityManager.getFlushMode() COMMIT

A little confuse..!

I assume the flushMode in the annotation is information for the interceptor and not necessarily true when viewed from within.

JPA doesn't have a concept of Manual flushing. When you set the flush-mode to manual in Seam, seam basically sets the JPA flush mode to COMMIT (so the EntityManager doesn't flush automatically) and queues all the statements until you call flush.
