Hi,
if anyone is interested ...
I implemented a solution mapping the collection with a where clause.
Thus, the collection will hold exactly one item.
>>>
...
<set name="Users" table="User" lazy="false" where="PRIMARY_USER=1"
fetch="join" cascade="all">
<key column="COMPANY_ID"/>
<one-to-many class="User"/>
</set>
..
<<<
The mapped class additionally provides a derived property which reads
this single element from the collection. The collection itself is
hidden from the client by the use of an interface the client uses.
If there's some other way I could do this, I would like to know ;)
kind regards,
Marc
