Yes, WebGrid (kind of smart web table) caches presented objects in 
session presentation state (instances of your Apps, that is subclasses 
of WebApplication) until you clean up that state. Because Aida web apps 
don't have a session timeout by default, this cleanup is done 
explicitly, usually every night.

But let we move this discussion back to Aida mailing list. Others can 
follow or join it here: http://www.aidaweb.si/community.html
