So I think you have to use this construction:
rule "interest calculation"
no-loop
when
$account : Account( )
then
modify($account) {
setBalance((long)($account.getBalance() * 1.03) )
};
End

Subject: Re: [rules-users] URGENT - using lock-on-active or not
Thanks
I have number of rules between the 2 rules, I just sent, that can get other
inputs that affect my decision to fire the second rule and update again the
case.
for example:
- at the beginning the case value is 80
- according to the first rule I update the case value to 40
- ....other rules...
- according to the previous rules I need to update again the case value - add 5
to the last value (40 + 5), but I get 80 + 5, because to working memory was not
updated with my updates (change to 40).

This is by design
http://lists.jboss.org/pipermail/rules-users/2009-March/008299.html
What are you trying to accomplish? There is no difference in the patterns you
are matching in both rules however you expect different consequences to occur
based upon salience. Based upon the foregoing link you could try changing one
rule to be in a different ruleflow-group however that could have other
consequences.

Hi All,
I have an urgent problem which I hope someone can explain it to me and how it
can be solved.
I created 2 rules "Update 1" and "Update 2", basically the rules are the same,
get all the CaseLog objects according to "Category" and "Value" and update the
Case, which holds a list of CaseLogs, with a new object.
Note that in the update method I am updating the working memory by retracting
the old log and inserting the new one.
Now for the problem:
The problem is that on one hand, when I insert a new log line all rules without
lock-on-active re-fire. On the other hand, rules with lock-on-active seem to
disregard the addition of the new object and fire only on the lines that were
present when their group was activated.
Please see the rules below
Thanks
Yaniv
rule "Update 1"
salience 4
ruleflow-group "group1"
lock-on-active
when
$case : Case()
$myLog : CaseLog( myClass == "Category",
myValue == "1" )
then
System.out.println("Logic: Update 1");
$case.update($myLog,40.0,null);
end
rule "Update 2"
salience 0
ruleflow-group "group1"
lock-on-active
when
$case : Case()
$myLog : CaseLog( myClass == "Category",
myValue == "1", $score : myScore )
then
System.out.println("Logic: Update 2 " + $score + 5.0);
$case.update($myLog,$score + 5,null);
end
