> Seam does not guarantee component lifecycles for SFSB backed components.  
> The container controls when SFSB's are removed / timed out.  When Seam accesses an SFSB that has been removed by the container, it results in an EJBNoSuchObjectException.
> The JBoss specific workaround for Session scoped components is to use the @CacheConfig annotation, setting the idle timeout to match the HttpSession timeout.  Similar changes would have to be made to any Conversation scoped component that uses a timeout greater than the default SFSB timeout of 5 minutes (which just happens to be the default timeout for Seam conversations).
> There is no workaround for Application scoped components.  Once removed by the container, EJBNoSuchObjectException's will continue to be thrown as Seam tries to access them.
> Seam's context model needs to somehow guarantee that its SFSB instances aren't removed by the container before Seam is finished with them.  And/or, it needs to recover from EJBNoSuchObjectException's more gracefully, especially with regards to Application scoped components for which there is no workaround.
