[rules-users] drools 5.5 property reactive issue

I am seeing a weird pattern(or at least unexpected one) when running drools 5.5 in property reactive mode. I have to rules such as: rule "Rule 1" when $order:Order(orderType=="A", orderVolume>1000) then insert(new Charge($order,"code1",-.25)); end rule "Rule 2" when $order:Order(orderType=="A") then insert(new Charge($order,"code2",-.24)); end rule "Set best price" when $order:Order($id:id, $setCharge:charge) $charge:Charge(orderId=$id,$setCharge==null || chargeAmount<$setCharge.chargeAmount) then modify($order){setCharge($charge)}; end If I insert and Order of 1001 I see all 3 activations get created, Rule 2 fires first thus triggering set price rule and the activation of Rule 1 is cancelled. If I add a @watch(charge) to the end of the rules or set up salience Rule 1 fires. Could someone help me understand why the firing of Rule 2 and thus the set best price rule cause rule 1 to get cancelled without the @watch? -- View this message in context: http://drools.46999.n3.nabble.com/drools-5-5-property-reactive-issue-tp40...
