Re: [rules-users] Can we fire a rule from another rule...?
I have some reservations w.r.t. the proposed solution. One has to assume
that "Rule 2" is there (and should continue to be so) to fire when its
condition is true, irrespective of what goes on due to "Rule 1". The only
way to do this is by writing
InsertedFact()
or
condition-of-rule2()
and this would make any bindings in condition-of-rule2() unusable in the
rule's consequence.
If by "firing" is meant that the RHS of Rule 2 is to be executed, simply add
the statements of the consequence to the ones of Rule 1. (Wrapping it in a
function avoids code duplication.)

Insert a new fact that causes Rule 2 to fire. That way you can
decouple
your logic and gain more flexibility to add more rules based on this new
fact.
