[jboss-user] [JBoss Seam] - Bug? Object with session scope randomly injected or not

[chris@dvdb.de]

Hi!

I'm extending frameworks EntityQuery and injecting a session scoped object:


  | 	@In(scope = ScopeType.SESSION)
  | 	Mediabase mediabase;
  | 

If I paginate through the resultList the object is sometimes null (that means: on one result page it is not null, on second result page it might be null or not etc.). Even reloading the same result page sometimes gives me an exception sometimes not.

Here is the stacktrace:

Is it a bug or is it me :D?
