  I'm running into problems with injection for persistence context. If in a session bean I do:
@PersistenceContext private EntityManager em
  everything is fine, however if in the Seam component I do:
@In(create=true) EntityManager em
  the application breaks up and I get:

  | Caused by: org.jboss.seam.RequiredException: In attribute requires value for component: newAuction.em
  | 	at org.jboss.seam.Component.getInstanceToInject(Component.java:1882)
  | 	at org.jboss.seam.Component.injectFields(Component.java:1348)
  | 	at org.jboss.seam.Component.inject(Component.java:1118)
  | 	at org.jboss.seam.interceptors.BijectionInterceptor.bijectNonreentrantComponent(BijectionInterceptor.java:76)
  | 	at org.jboss.seam.interceptors.BijectionInterceptor.bijectComponent(BijectionInterceptor.java:58)
  |         ...

  Any ideas what may be wrong? I was thinking that maybe it's because I'm using Trinidad and according to the documentation I had to turn off the Seam view handler in web.xml (http://wiki.apache.org/myfaces/Facelets_with_Trinidad)
  When I keep it indeed I get a Trinidad error:

  | java.lang.IllegalStateException: No RenderingContext
  | 	at org.apache.myfaces.trinidad.render.CoreRenderer.encodeBegin(CoreRenderer.java:159)
  | 	at org.apache.myfaces.trinidad.component.UIXComponentBase.encodeBegin(UIXComponentBase.java:667)
  Can it has something to do with that? Any help appreciated!
