Thank’s for your sugession of using “not in” instead of “not” but my problem is that “not” can also come without “in”.

 

Actually I am making a generator of rule file from expression like

 ((NOT (ENDS WITH (G10.2, ",")))

 

 ((NOT (G13.1 IN ("1","2","3"))) OR (G250.8 = Y)))

 

Where G13.2, G250.8, G10.2 are variables coming from a map inserted in working memory.

 

I am accessing these variables from map.

 

My rules are as follows

 

This rule is working fine.

 

rule "Editable_G10.3"

when

 

 ((Map( this["G10.3"] !=8))||(Map( this["G10.2"] ==19)))

 

then

System.out.println("comming here----------------------------------------------------->");

End

 

This is not working

 

rule "Mandatory_G10.3"

when

 (not((Map( this["G10.3"] !=8))||(Map( this["G10.2"] ==19))))

Then

System.out.println("comming here----------------------------------------------------->");

End

 

In also tried following approaches:

1)      eval(not((Map( this["G10.3"] !=8))||(Map( this["G10.2"] ==19))))

 

2) eval(!((Map( this["G10.3"] !=8))||(Map( this["G10.2"] ==19))))

 

But in both cases it is giving same error:

org.drools.rule.InvalidRulePackage: Rule Compilation error : [Rule name=ValidationRuleExp_G10.3, agendaGroup=MAIN, salience=0, no-loop=false]

      com/telekurs/nva/mde/fe/ak/validation/Rule_ValidationRuleExp_G10_3_0.java (11:495) : Cannot use this in a static context

      com/telekurs/nva/mde/fe/ak/validation/Rule_ValidationRuleExp_G10_3_0.java (11:500) : Type mismatch: cannot convert from String to int

 

I am trying to find out some general concept so that I can change just achieve the functionality of not.

 

Thanks

Gaurav

 

 

   Remove your "eval" and use "or" instead of "||" for the OR CE.

   Although, I feel that this is not what you want... what you want is simply:

when
    Map( this['city'] not in ( "mumbai", "delhi" ) )
then
    //...
end
