I had some time today so I made an attempt at creating injectable
EntityListeners. After wandering for quite some time deep in the CDI land,
I had to pull out and decided that I really don't want to include all the
CDI container dependencies just make my entity listeners injectable. After
that, it was pretty simple although I had to use a provider (Eclipselink)
specific api:
ServerSession session = entityManager.unwrap(ServerSession.class);
session.setEntityListenerInjectionManager(new
EntityListenerInjectionManager() {...}
With a little advice, I can now have all my entity listeners available to
JPA and inject any tapestry services on them on via constructor injection
(that we all know and agree is far superior to setter/field injection...).
If they add this to the JPA api in a future version, I'll make a little
library for it.
