In this case the error is occurring outside of a cfc. I'm performing a QoQ on a query that's returned by a cfc function. The query is var scoped and constructed from data returned by a web service. Maybe I should be duplicating it as it's returned (?).
@Kai ... What about one of those JVM inspection tools, do they show exceptions as they occur? Maybe we can see it there?
