Wolfgang,

The ActorType definition is here: https://github.com/openhealthdata/CCR-Validator/blob/drools5.0/src/main/java/org/astm/ccr/ActorType.java

The point of this rule (and the other rules in this package) is to "walk" through a very complex object graph and insert the objects into working memory.

Should this this single file ActorType.drl be doing all of these insertions? Then I don't think this is going to work (but not related to the NPE).

Does the problem occur if you use just this file?

I do not use the rule attribute "dialect". The drl in question is here: https://github.com/openhealthdata/CCR-Validator/blob/drools5.0/src/main/resources/rules/core/ActorType.drl

I tried to create a simple project that caused the same error, but I create a Class with inner classes similar to ActorType and write a rule like the one in question, but it does not cause the error.

Thanks,
Steven

Please provide the type declaration for ActorType.Person, field gender and
typicial examples how gender fields are used in other rules. Ideally, if you
could reduce your rule set to this simple rule and one other rule, still
causeing the same problem.

Also, do you use "dialect 'mvel'"?
