Re: [rules-users] Dynamic updates of stateful sessions

@Wolfgang, maybe I need to update the documentation to explicitly inform about this behavior :).

The agent doesn't make anything special to sync the sessions with the kbase. If you add a rule by hand to an existing kbase, all the session from this kbase will automatically detect the changes. Now I'm working in a helper class to create and apply change-set in a programatic way. So if you don't want kbases to be automatically modified when a resource chages, you can use this helper class.
