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

Hello All, 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 ------------------------------------------------------------------------------------
