<DIV></DIV>IMO you can just use activation groups and not have to deal with
incrementing, something like:<BR><BR>rule first<BR>activation-group
"myactgrp"<BR>when<BR> Condition A<BR> Condition
B<BR>then<BR>...<BR>end<BR><BR><BR>rule second<BR>activation-group
"myactgrp"<BR>when<BR> Condition A<BR> Condition
C<BR>then<BR>...<BR>end<BR><BR>rule third<BR>activation-group
"myactgrp"<BR>when<BR> Condition B<BR> Condition
C<BR>then<BR>...<BR>end<BR><BR>When one of these rules fire it will cancel the
activation of all other rules in the same activation group. You can also then
add salience to control rule priority.<BR><BR><BR>On 6/3/10 8:15 AM, PAYET,

Of course, if you change the fact, you'll probably have to think about things like lock-on-active to increment only one time the cnt variable

Objet : [rules-users] Firing a rule if at least its two conditions are satified
Hello,
we are using Drools in our company. We have a rule with three conditions in this format:
when
Condition A
Condition B
Condition C
then
execute Action 1
Now we have a situation, in which the rule should fire if AT LEAST two of the three conditions are satisfied. Do you know how to implement this? Any ideas or hints?
Many thanks and regards!
skasab2s.
