Same happened to a mate upgrading to the latest snapshot. A default value as suggested by Jeremy would be ok.
Jeremy, did you see the mail at [1] ? It's intent was to solve your idea of a "generic" Spec Transformer for Isis entities. There I copied the code of a generic class. I'm testing an improved version and plan to commit it next week (in fact, 1 abstract class with 2 specializations; one allowing null entities, and one throwing an exception if the referenced object is not found - as normally is a "transcription" problem). If you want to previously access it, don't hesitate to ask and I can attach current version to a JIRA ticket.
