1-1-Mapping: Referenced field must be primaryKey???
Hi,
junit: Article - Produktgroup
Article holds an ID from Productgroup. In the example it is the
primaryKey from table Kategorien.
Can I use different field for it?
i get the message:
WARN: OJB broker could not materialize ....AbstractPersistent{1332}
The number shown is the fieldvalue i want to use for referencing the
productgroup.
But the IndirectionHanler uses the primaryKey (which in my case can't fit)

hi thomas,
is the primary key in the repository allways primary key of the
database-table?
or do they only have to be unique values?

foreign keys from one table alway reference primary keys of another (or
the same in case of self-join) table.

only by declaring it as primary key in the repository.
