If I could attach the code I would.... but since I see no way, here's some more
inline code.
I modified the booking application and deployed it on both 4.2.1GA and 4.2.2GA,
both of which appear to have the same FlushMode issue.
In addition to my changes to get it working with JSF 1.2 RI I did the following:
Added the following properties to persistence.xml - to create a smpc:
| <property name="jboss.entity.manager.factory.jndi.name"
value="java:/entityManagerFactory"/>
| <property name="jboss.entity.manager.jndi.name" value="java:/em"/>
|
Added the following to components.xml - to create a smpc:
| <core:managed-persistence-context name="entityManager"
| auto-create="true"
| persistence-unit-jndi-name="java:/entityManagerFactory"/>
|
My new HotelBookingAction (I tried to bold the changes but that didn't work
because they are in a code block):

This causes the booking to be persisted when you set it's details. When you
confirm the details, the entityManager is flushed.
To test this just create 1 booking and cancel on the confirmation page. Then
create another booking and confirm it. You will see both of the bookings in
your list now.
Thanks,
Austin
