Michelle Caisse resolved JDO-193.
---------------------------------
Resolution: Fixed
JDO-430 is now tracking the remaining issues on this case.
> Need new test cases for Map and List where there is no join table; the key is a field of the value type or the value is a field of the key type

>
> JDO allows mapping of Maps where there is no join table. The metadata for the Employee/Department mapping uses the mapped-by attribute of the map element:
> <class name="Department">
> <field name="employees" mapped-by="dept">
> <key mapped-by="id"/>
> </field>
> </class>
> <class name="Employee">
> <field name="id" column="ID"/>
> <field name="dept" column="DEPT"/>
> </class>
> Another mapping would have the key of the Map be the Employee and the value be the id.
> We should probably define a separate package for this mapping, as there is some confusion in using parts of the Company model where we have changed a significant part of the model.
