Re: [rules-users] Rules with from always loops (Drools 4.0.7)

Hello, Doesn't really anyone have any logical explanation of why such a rule loops? To remind the rule: rule "Hello World" no-loop when $fact1 : MyFactBean1( ) $fact2 : MyFactBean2( ) from $fact1 then System.out.println("Fired!!!"); update($fact1); end If I don't use 'from' everything is fine. I really didn't find in a documentation, that 'from' causes any special behaviour of the rule looping. Best regards, -- Przemysław Różycki AMG.net, A Bull Group Company ul.
