[rules-users] error with firing of rules and chainig rules

[Giovanni Motta]

When you update your objects, do you notify the session of the change?
If you do that, you should not take care of salience. The objects insertion
order is not relevant (or, at least, marginally).
To notify the session of an object change, you should either put your
modifications inside a 'modify' block (see the docs) or let your java beans
include a 'PropertyChangeSupport' field (see dynamic facts).
In your sample, when the room gets the 'fire' status, the session should be
notified of the change, and the sprinkler rule will fire.
