Exception accessing T5 Registry from other servlet

[Inge Solvoll]

Hi!

I'm trying to integrate my T5 IOC Registry with the non-T5 part of our
application. But when I try to actually use services that are perthread and
depend on session data, I get the error listed below. It seems that the
request or the session hasn't been initialized properly for the request.
This is a request for a page that is in my "ignoredPaths" list, so it is
ignored by tapestry. Is that the reason why I get this error? Or is it
perhaps affected by the order of my servlet filters?

Here's the service implementation with the error:

public class UserWrapperImpl implements UserWrapper {

private final ApplicationStateManager asm;

  public UserWrapperImpl(ApplicationStateManager asm) {
    this.asm = asm;
  }

  public User getUser() {
    return asm.get(User.class);
  }

}
