[rules-users] inconsistent behaviour with 'not' keyword

Hello Simplified version of my rule is given below. Since I want to run this rule once once, I control it using Bar() fact. This rule fired inconsistently(i.e sometime it fired, sometime it is not). I could not also reproduce. Does anybody have the clue for this? Thanks for the help. rule "run once" list : ArrayList(size > 0) from collect(Foo()) not Bar() then insert(new Bar()); end -- View this message in context: http://www.nabble.com/inconsistent-behaviour-with-%27not%27-keyword-tp232...
