Interceptors can execute code before and after an Action is invoked. When is yours being invoked? I would imagine what's happening is this:

  • In LogOutUserAction.java you invalidate the session
  • LoginInterceptor.intercept is then executed. This tries to get an attribute from the session object that you invalidated hence the IllegalStateException.

Why are you invalidating the session? Your LoginInterceptor is using the presence of the USER_HANDLE attribute to indicate whether or not the user is logged in. I would remove this attribute in your LogOutUserAction but don't invalidate the session.
