Equivalent of Seam 2 Component

[idyoshin]

Sometimes I've been using code like  (EntityManager ) Component.getInstance("entityManager")  or Component.getInstance(SomeController.class)

That I've been using in some @Transitional methods in my entities. I understand  that now I can rewrite everything with controller's and el functional calls with params like  #{someController.process(someObject)}

But I'm very interested in facade for components in cdi.  Maybe it's already present and I haven't found it yet?

Any advise would be great.
Kind regards,
Ilya

@Inject SomeController controller;

equals to Component.getInstance(SomeController.class). Component wasnt typesafe anways...

[idyoshin]

I understand that. 

What I'm talking about: I've been able to receive the component in non-managed bean. For example entityBean, which is not managed by seam (now cdi) container.

I remember hearing something about this, but I don't remember where it ended up, I think Stuart could comment on this. It very well may be possible, but might need a bit of a bridge of the two technologies.

In case I have to replace the below in SEAM3 :

EntityManager entityManager = (EntityManager) Component.getInstance(em); (org.jboss.seam.Component)

Then what will be the equivalent.

And also for @org.jboss.seam.annotations.faces.Converter and @Transactional

there is no Component in seam3...use BeanManager to find bean manually.
or use @Inject on a bean property directly.

Please read the Seam Persistence docs for how to create a producer for the entity manager, and declarative transactions. As for the Converter JSF 2 has an annotation for that, you can also take a look at the Seam Faces docs.

what will be the equivalent for @Converter.
