Shouldn't that have been: $foo : Foo (myEnum == MyEnum.someItem) Your field is presumably "myEnum", whereas the class is "MyEnum".

Please raise a JIRA for Guvnor and attach your model JAR. I will take a look.

Thanks, it deserves investigation. There seems to be at least a bug in Guvnor - it should create a constraint such as : Foo( myEnum == MyEnum.someitem ) On 04/18/2013 10:19 AM, Sean Su wrote: I am using 5.5.0.Final and I think I may have run into a bug. Assuming I have a class Foo that has a getter which is getMyEnum(). Also I have a Enum class which happens to have the name MyEnum. When writing rules, I have $foo : Foo (MyEnum == MyEnum.someItem) This line will throw NullPointerException. I have to write it as: $foo : Foo (getMyEnum() == MyEnum.someItem) This statement will work just fine. The workaround is ok for DRL. However I tested this on Guvnor and the rule editor would generate the DRL just like the first statement (MyEnum == MyEnum.someItem). So we would be out of luck there. Has anyone ever ran into this before.
