Re: [rules-users] Bizarre bug or user error:

Wolfgang - Thanks for your reply. As I said in the original subject line -- bizarre bug or user error? Well, it turns out to have been user error -- There was another rule in the rulebase that was altering values on the PolicySet objects, but failing to update() them. This caused the Rule Engine to evaluate using old matches and produced wrong results. If you did file a JIRA, you can probably cancel it. -- <red faced> -- Sorry for the confusion.
