[jboss-user] [JBoss Seam] - SeamExtendedManagedPersistencePhaseListener ?

[lcoetzee]

Hi,

I am tracking Seam's CVS. Some changes done very recently (over the weekend or Friday 15/06/2007) is creating some weird things.

I see that there is no more SeamExtendedManagedPersistencePhaseListener. I have taken that out from my faces-config.xml. I assume that the normal SeamPhaseListener will do al of these things automatically. However, since I have taken it out I get the following exception:

12:37:09,956 ERROR [SeamPhaseListener] uncaught exception

  | 


Looking at the Seam example I see that they use 
@PersistenceContext(type=EXTENDED)
  |    private EntityManager em;
  | 

while I use 
  |  @In(create = true, value = "napEntityManager")
  |         private EntityManager em;
  | 

Is the above part of my problem ? 

Regards

Louis
