[rules-users] Rules not firing when facts asserted in a rule RHS in 5.0

I have been using the open source Drools 5.1 where I have been inserting facts in the RHS of a rule and that has been causing subsequent rules to fire just fine. However, I am working at a customer that requires my to use a supported product, so I have moved my rules over to JBoss Rules 5.0.2 and I find that this does not work any more. I have a declarative fact type as follows declare QuestionValidation question: String state: String mandatory: Boolean type: String end I have an "init" rule with high salience that inserts a number of QuestionValidations into the session. In order to test what is going on, I created a rule:- rule 'Test' dialect 'mvel' when $qv: QuestionValidation() then System.out.println( "QuestionValidation found " + $qv.getQuestion() + "/" + $qv.getState() ); end This rule never fires if I insert a QuestionValidation in the init rule! I can see the facts being inserted in the log as follows [#|2010-12-01T09:19:16.723+0000|INFO|sun-appserver2.1|javax.enterprise.system.stream.out|_ThreadID=70;_ThreadName=p: thread-pool-1; w: 7;| OBJECT ASSERTED value:QuestionValidation( mandatory=true, state=Closed, question=B2B_METER_SERIAL_NUMBER, type=string ) factId: 39|#] But I don't see any associated "ACTIVATION CREATED" for this object. However, if I insert a QuestionValidation fact created in Java by using kbase.getFactType("SWWB2BOutgoing", "QuestionValidation") then the Test rule gets fired just fine. Is there something I am missing? Do I need to to turn on rule chaining or something like that? (Surely chaining is on by default). Chris
