[rules-users] Not able to achieve NOT & FROM keyword in a brl through Guvnor

[Harshit Bapna]

Hello All,

>From the Expert documentation, I am trying to create the rule(below) in
Guvnor
 Guvnor Version : 5.1.1

I am not able to build a rule which has 'from' keyword. Is it supported in
Guvnor ?
Also I am not able to achieve the combination of NOT & FROM in a business
rule.
Is it possible ?

------------------------------------------------------------------------------------
package org.drools;

rule "Avoid NPE on wrong syntax"
   when
     not( Cheese( ( type == "stilton" && price == 10 ) || ( type == "brie"
&& price == 15 ) ) from $cheeseList )
   then
     System.out.println("OK");
end
------------------------------------------------------------------------------------
