I have double-checked and can confirm I am using the only non-static
marshall
method: marshaller.marshal(instance);
I can also confirm the mapping file is being loaded and used, as when I
remove
the declarationItem reference from the underlying bean class, the objects
are
marshalled according to the mapping file definitions - the fields marked
transient do not appear in the marshalled xml.
Similarly the multi-word field names (ie: declarationText) are marshalled
according to the default naming convention (ie: to declaration-text).
Could this problem be related to any particular properties file setting?
Is there anything else you need to configure to get references working?
Of note, the stack overflow excpetion appears to revolve around hashCode
generation methods. I have included a copy the Declaration class source
below
for reference to this (80 character limit prevents both from being posted).
Likewise the DeclarationItem
hashcode method references the Declaration class in the same way....
Thanks,
Damian

Damian,
Are you certain that Castor is using your mapping file? Your xml names
are the same as the default introspection names so it may be that Castor
isn't actually using your mapping file. Make sure you are not using one
of the static marshal methods.
