hi peter,
imo this is on the to-do-list. as a workaround you can still use extents
and super-references but you should take care that the primary key is
UNIQUE within the class hierarchy.
for further details hava look at the thread: Extents and the various
inheritance hierarchy mappings in
Hi,
I try to map two classes Address and PersonAddress (a subclass of Address)
using the joined table per sublcass strategy. This is my mapping:
class-descriptor class=de.armax.sandbox.entity.Address
table=Address
field-descriptor autoincrement=true primarykey=true
column=adrOID
.
Cheers,
Greg Plummer

Try refresh=false on the super reference.
Does not work either. I tried
refresh=false
auto-retrieve=false
auto-delete=false
auto-update
Well, that's what I tried resulting in a StackOverflow error. I guess it has
to do with the auto-update, auto-delete and auto-retrieve attributes of the
super reference-descriptor in the subclass. Could anyone tell what
settings for those attribute are needed/possible for a correct mapping of
Hi Peter,

hi peter,
you could try to define an extent in classdescriptor of Address pointing
to PersonAddress. BUT the problem is that extents and super-references
do not go together well. you may end up with instances of the wrong
class. the support for mapping one class to multiple tables needs
