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

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

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
