Arsalan,<br>
<br>
Unfortunately Drools does not have a field constraint
negation operator, mostly because when writing rules, it was not needed, since
you can always negate the constraint itself. <br>
Although, I understand a agree with your use case. My
suggestion is for you to open a JIRA feature request and we will include that
as soon as possible in the product. <br>
Although, meanwhile, the only workaround I can see for your
case is to translate the expression you are using directly into a java or mvel
expression and write it inside an in-line eval.<br>

Remove your "eval" and use "or" instead of
"||" for the OR CE.<br>
<br>
Although, I feel that this is not what you want... what you want
is simply:<br>
<br>
when<br>
Map( this['city'] not in ( "mumbai", "<st1:City
w:st="on"><st1:place w:st="on">delhi</st1:place></st1:City>" ) ) <br>
then<br>
//...<br>
end<br>

Hi ALL,<br>
<br>
I am using drool4.0.1 in my application i am able to use IN,OR,AND operator<br>
but i am facing problem in using not operator.<br>
<br>
my requirement of not operator is just like a not gate.<br>
<br>
the way i am using it is : <br>
<br>
eval(not((Map( this["city"] !="mumbai"))||(Map(
this["city"] =="<st1:City w:st="on"><st1:place w:st="on">delhi</st1:place></st1:City>"))))<br>
<br>
<br>
so can you please help me out to solve this problem:<br>
should i use not operator or some thing else in drool. <br>
<br>
Thanks,<br>
<br>
<br>
