5.2.0.Final I am seeing some confusing behaviour in enum comparisons in LHS rule conditions. I have an enum class, "Status" (full source below) that is an attribute on several of our domain objects. I'm comparing the enum in several ways, and the rule fires differently when I use syntax that AFAIK ought to have the same result. for example, say there is a Step with status of Status.PENDING. if I write: $step : Step(status.active == false) // rule DOES fire $step : Step(status != Status.ACTIVE) // rule does NOT fire, but should I am testing this with the same objects and same test each time. can anyone explain why the two comparisons do not get the same result? here is the definition of Status: public enum Status { PENDING("Pending"), ACTIVE("Active"), COMPLETE("Complete"); private final String label; private Status(String label) { this.label = label; } public String getLabel() { return label; } public boolean isPending(){ return label.equals("Pending"); } public boolean isActive(){ return label.equals("Active"); } public boolean isComplete(){ return label.equals("Complete"); } public static boolean isPending(Status status) { return (status == null) ? false : status.isPending(); } public static boolean isActive(Status status) { return (status == null) ? false : status.isActive(); } public static boolean isComplete(Status status) { return (status == null) ? false : status.isComplete(); } public static Status fromString(String name) { if (name != null) { Status types[] = Status.values(); for(Status s : types) { if (name.equalsIgnoreCase(s.toString())) { return s; } } } return null; } } -- View this message in context: http://drools.46999.n3.nabble.com/confusing-behaviour-of-enum-comparison-...

thank you for taking the time to test this, Wolf. I have other tests with the same syntax that have tested ok as well. It is puzzling. I will test tomorrow with the mvel jar that I'm using. I went to the beta 6 mvel because it compiles a lot faster for 5.2 but perhaps there are side effects. -- View this message in context: http://drools.46999.n3.nabble.com/confusing-behaviour-of-enum-comparison-...
