[rules-users] Problem with CEP/Fusion rules in Guvnor and RuleAgent: unable to determine operator for symbol [after]
Hello Drools users
Given the following simple test rule:
rule "test rule 1"
when
$e : Event();
not( Event(id == $e.id && this after[0s,10s] $e ) )
then
System.out.println("Hello");
end
placed in Guvnor and the following simple test project:
ruleagent.properties:
url=http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/defaultPackage/LATEST
TestRuleAgent.java:
RuleAgent agent = RuleAgent.newRuleAgent("/ruleagent.properties");
RuleBase rb = agent.getRuleBase();
throws the following exception:
Exception in thread "main" org.drools.RuntimeDroolsException: unable to
