Craig Russell updated JDO-193:
------------------------------
Fix Version: JDO 2 final
(was: JDO 2 rc1)
> Need new test cases for Map 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
> ---------------------------------------------------------------------------------------------------------------------------------------

> Key: JDO-193
> URL: http://issues.apache.org/jira/browse/JDO-193
> Project: JDO
> Type: Test
> Components: tck20
> Versions: JDO 2 beta
> Environment: TCK
> Reporter: Craig Russell
> Fix For: JDO 2 final
>
> 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.
