hello everybody and thanks for the great job you have done!

i have an application running on jboss 4.0.4.GA with seam 1.0.0.GA and myfaces 1.1.3.  i've been working on this application for a while, 
i'm in the test phase now. i use many converation scoped session beans
 as actions for the pages and some session scoped sesson beans to encapsulate business logic which are used by the action beans. now i noticed a problem: 
when a action component and the business component
 it uses get invoked and the app is not used for a while i get strange errors. when i try to use a component after about 10 minutes idle time an error occurs.
 after 30 minutes of idle time the same error happens when the container tries to destroy the components.

here are the exceptions (boconfirmation is the business component, loaddata is the action component):
