> When modifying the insurance sample RuleFlowTest.java class to use sequential mode with stateless session and calling a ruleflow from a rule, I receive the following error:
> java.lang.ClassCastException: org.drools.common.ArrayAgendaGroup incompatible with org.drools.common.BinaryHeapQueueAgendaGroup
> Here is more detail:
> Inside RuleFlowTest.java ...
> ...
> RuleBase ruleBase = readRule();
> StatelessSession statelessSession = ruleBase.newStatelessSession();
> StatelessSessionResult statelessSessionResult = statelessSession.executeWithResults(facts);
> Inside readRule() I have ...
> ...
> RuleBaseConfiguration conf = new RuleBaseConfiguration();
> conf.setSequentialAgenda(SequentialAgenda.SEQUENTIAL); //I also tried without this line
> conf.setSequential(true);
> Inside rule (drl) I have:
> rule "startRuleFlow"
> 	salience 1000
> 	when
> 	then
> 		drools.getWorkingMemory().startProcess("process.name");
> end
> The error occurs in the RHS above.
