[rules-users] What if Rules change frequently...

[Edson Tirelli]

   James,

   It may not be "easy", but one way is to use the dynamic rules feature 
from JBoss Rules. This way, you assert facts into your rule base with 
your current rules. When a rule/package changes, you remove that 
rule/package from the rulebase and add the new one. JBoss Rules takes 
care of creating the new activations for you based on existing facts, 
but you need to be aware that such activations will be created even if 
it was already fired for the old rule.
