Re: [rules-users] Help on writing a rule

Hi Guys. I have one quesiton on how could I implement my rule. I have this rule: when t : PriceChange() over window:length(1) signal : Signal( id == "1234" ) over window:length(1) not OrderCreated( id == "1234" ) over window:time (1m) then insert(new OrderCreated("1234)); Basically, when there is some signal and some price change, create a new order if there has no been any other order in the last minute. But this sometimes is being fired twice: 12:31:01,121 INFO [org.drools.audit.WorkingMemoryConsoleLogger] (Camel (camel-1) thread #4 - JmsConsumer[marketDataTopic]) ACTIVATION CREATED rule:ertetr activationId:ertetr [393, 392, 0] declarations: t=PriceChange [](392); signal=Signal@1413ddef(393) 12:31:01,160 INFO [org.drools.audit.WorkingMemoryConsoleLogger] (Camel (camel-1) thread #4 - JmsConsumer[marketDataTopic]) ACTIVATION CREATED rule:ertetr activationId:ertetr [393, 394, 0] declarations: t=PriceChange [](394); signal=Signal@1413ddef(393) I think that, when the 1m window have passed, it creates twice the activations, as I have not called fire all rules yet. Does is make sense? Do you have some idea on how could I implement this rule? "when there has been some price change and some signal, and I did not create a new order in the last minute, just create a new order". Thanks in advance!
