Hey all, I've got a rule in a DRL file that I'm trying to call an object method that contains a varargs parameter. The method signature looks like so: public void addMessage(int displayPriority, String messageFormat, Object... messageArgs) { The rule looks like so: rule "Notice Quantity" no-loop when $notice : Notice(quantity > 0); then $explanation.addMessage(1, "%s Quantity = %,d", $notice.dispositionCode, $notice.quantity); end When I run this rule base, I get this runtime error from the Drools engine: Caused by: [Error: unable to resolve method: com.package.TriggerExplanation.addMessage(java.lang.Integer, java.lang.String, java.lang.String, java.lang.Integer) [arglength=4]] [Near : {... Unknown ....}] This feels very much like either the MVEL engine or Drools can't resolve a method with varargs. I found nothing in any of the documentation and the only thread on these forums that references varargs was a few years old. Can anyone tell me if Drools does/does not support method calls with varargs? Doing this without varargs is going to be a galactic pain in the butt. Thanks!
