Dennis Sosnoski resolved JIBX-19:
---------------------------------
Fix Version: CVS
Resolution: Fixed
The JiBX code generation is unable to handle references embedded directly in a
collection. I've supplied custom marshaller/unmarshaller base class examples
(which need to be subclassed by the user) as org.jibx.extras.IdRefMapperBase
and org.jibx.extras.IdDefRefMapperBase which can be used within collections as
long as there are no forward references; for forward references you'd need to
take these and extend them to handle the whole collection, with backfill
generation. I've also added a check for using a reference directly within a
collection as a binding error, so that users will know when they're doing
something that's not supported. That's the best we can do on this, at least
until 2.0.
