JAXBians,
Actually, i have groveled through the source a bit and i suspect this to be
a bug. All of the necessary context to resolve this reference actually lives
on the DelayedRef object stored on the ElementDecl in its type field. It
looks as though resolve was never called for this type, and thus ref was
never set. i can't be sure at this point, but if anyone knows anything about
this, i'd love to hear from you.
Best wishes,
--greg
