Hi folks, I have defined some rules in Eclipse and tested with JUnit tests and everything was fine. Now I defined the rules in Guvnor and while validating I get the following error: [CardTrapping] Unable to Analyse Expression Fraud fraud = new Fraud(Fraud.CARD_TRAPPING, new SSTEvent[] { $event1, $event2, $event3, $event4 }); fraudControl.handleFraud(fraud);: [Error: expected type: com.wn.fraud.droolstest.model.SSTEvent; but found: com.wn.fraud.droolstest.model.SSTEvent] [Near : {... SSTEvent[] { $event1, $event2, $event3, $event4 }) ....}] ^ [Line: 1, Column: 70] I have imported my data model, before creating the rules, therefor for the type SSTEvent an import is defined. But it seems, that the type SSTEvent exists with different versions? I have this problem for each rule, when I'm using the SSTEvent type in the "then" case. Here the complete rule defintion: package com.wn.fraud.droolstest import com.wn.fraud.droolstest.model.Fraud; import com.wn.fraud.droolstest.model.FraudControl; import com.wn.fraud.droolstest.model.SSTEvent; global FraudControl fraudControl; rule "CardTrapping" when $event1 : SSTEvent ( eventNumber == SSTEvent.CARD_JAMMED ) from entry-point "device-event-stream" $event2 : SSTEvent ( this after [ 0s, 30s ] $event1, eventNumber == SSTEvent.IN_SERVICE, deviceId == $event1.deviceId, branchName == $event1.branchName ) from entry-point "device-event-stream" $event3 : SSTEvent ( this after [ 0s, 30s ] $event2, eventNumber == SSTEvent.CARD_JAMMED, deviceId == $event1.deviceId, branchName == $event1.branchName ) from entry-point "device-event-stream" $event4 : SSTEvent ( this after [ 0s, 30s ] $event3, eventNumber == SSTEvent.IN_SERVICE, deviceId == $event1.deviceId, branchName == $event1.branchName ) from entry-point "device-event-stream" then // inform fraud control Fraud fraud = new Fraud(Fraud.CARD_TRAPPING, new SSTEvent[] { $event1, $event2, $event3, $event4 }); fraudControl.handleFraud(fraud); end Thx a lot for help! -- View this message in context: http://drools.46999.n3.nabble.com/Drools-Guvnor-validate-a-rule-results-i...
