[rules-users] not operation available in drools

[learner]

I have a scenario like below 

Rule a 

When 

! ( 

(aaa == “bbb”)  

(bbb == “aaa”) 

) 

Then 

// do smth 

End 

I’m looking for an operator to reverse the evaluation result of the
expression in the brackets. Is this possible

[rules-users] Else condition in drl file

[learner]

Hi,

I have a scenario like

if(value == 200){
  // then do something
}else if(value == 100){
// then do something
}else{
value = 0
}

I created drl with 3 rules
Rule 1 : value  equal 200
Rule 2 : value  equal 100
Rule 3 : value not equal to 100 or 200(ie by value!=200  value!=100 ).

Is there a way by which I can simplify the condition in rule 3.

Is there any exit statement in drl file to achieve the same.

[rules-users] how to use only updated value in drools

[learner]

I am having a drl file with 2 rules

The 1st rule updates a attribute, say updates attribute b to 10 based on
some condition.

The 2nd rule has a check for values with b not equal to 10. It logs error
for those values not equals to 10.

The b value gets updated to 10 in rule 1. However in the second rule it does
not use updated value and logs error.

Is there a way to use the updated b value in the 2nd rule. I tried using
modify but still the error gets logged.

Thanks for the reply.

Please find a basic structure of my drl file

rule set b value
  salience 10
no-loop
when
e : Person(b ==  );
then
e.setB(10);
end
 
rule b other than 10
  salience 1
 no-loop
 when
  e : Person(b != 10)
 then
   System.out.println(error+e.getB());
end

Modifying the condition does not fix the issue

It seems even though the value of b was modified to 10 in the first rule. It
considers b as only blank (initial value) in the When clause of second
rule.However in sysout the value of b appears properly as 10

The problem is the sysout gets printed in rule 2 , but it should not as the
value of b is modified to 10 in 1st rule

But since the b value is updated to 10 , is there a way to use this updated
value in second rule and not print any sysout.
