SeamManaged alternative to avoid LazyInitializationException

[aareshchanka]

I didn't found good way to avoid LazyInitializationException.

There are some discussions in this treads

But in seam-persistence 3.0 final I didn't found
annotaion @SeamManaged to provide transactions as mentioned in documentation for 3.0.0.Alpha1 and all CR's releases.

@ExtensionManaged
@ConversationScoped
@Produces
@PersistenceUnit(unitName="myPu")
EntityManagerFactory emf;

So question is how to avoid LazyInitializationException, what approach to do: phaseListener, producer, intercepter?

Can anybody provide example how to do it right?

Thanks, Alex.

If you're using Seam Faces, it uses a PhaseListener.

Actually I'm using seam-faces.

I took seam-booking sample and modyfied it, just added lazy connections with entites. I'm running application on as7 and getting such errors.

Do I need to add some specific configuration to seam-booking sample to turn on phase listener?

Thanks, Alex.

@SeamManaged was changed to @ExtensionManaged.

AFAIK this should be working correctly.

I enabled logging and that's true, phase listener is invoked correctly, but still LazyInitializationException occurs.

Does  seam-faces have tests for transactionphaselistener with lazyloading? Or maybe there is sample where entities are loaded lazily on the

page.

This exception ocures even if I load entity explicitly in managed bean by em.merge(entity) and the in xhtml envoke

1. {managedBean.entity.lazyProperty}

It seems to me that this functionality works incorrectly.
