I have the the following rule, rule "Validation" ruleflow-group "Validation" when $tar : MyObject() eval ($tar.validation() == true) then kcontext.getKnowledgeRuntime.signalEvent("ValidationError", null); end Where ValidationError is an external event defined in Flow. The problem I am having is if I defined the ValidationError event to be external, the signalEvent will get called all the time, and something $tar will become null when I try to print it out before the signalEvent call, but if I defined the ValidationEvent to be internal everything works as expected, but I just can't trigger the event because it is internal. Did I do anything wrong? Thank you for your help in advance. PS: I know I can trigger the internal event by passing the process object to the session, then trigger the event with the process object, but I really don't thnk this is a good design. -- View this message in context: http://www.nabble.com/Help-needed-for-a-weird-issue-when-firing-an-extern...
