Why does it need an ID field? Do the relationship keys not make it
unique? Can you make it an EOGenericRecord?

If you have an entity with no exposed properties incorrect SQL gets

to map between two other entities, it contains no data itself, just
two one:many relationships, and an id field, so three fields in all
(id, and two for the relationships). This causes SQL to be generated
'select t0.relationship1Id, t0., t0.relationship2 FROM ...'. If I
add a dummy data property to the entity you get 'select
t0.relationship1Id, t0.dummy, t0.relationship2 FROM ...' generated.
Seems that an assumption is being made that at least one exposed
property will exist for the EO. Is this likely to be the plugin or
the driver or WO itself?
Thanks
