The list should work fine as long as the thing it is a list of also works fine. Are there any annotations on DbRef? The issue really comes down to why is the typeQName null in this case. It should definitely not be.
Does a method like: int testDbRef(DbRef ref) work? Any chance you could create a small sample and attach to a JIRA?
