Andy Jefferson commented on JDO-215:
------------------------------------
I see that the MetaData is now, for example
<field name="HashSetOfObject1" table="HASHSET_OF_OBJECT1">
<join column="IDENTIFIER"/>
<element>
<embedded>
<field name="id" primary-key="true" column="ID"/>
<field name="intField" column="INTVAL"/>
<field name="stringField" column="STRINGVAL"/>
</embedded>
</element>
</field>
That certainly doesnt agree with my definition of a PK specification for the
join table. It should be (IMHO) like this
<join>
<primary-key>
<column name="IDENTIFIER"/>
<column name="ID"/>
</primary-key>
</join>
which nicely defines the colums to be used for the join table. Using fields of
an embedded object and specifying primary-key there is not logical to me, and
not supported by JPOX either. The JPOX online docs
http://www.jpox.org/docs/1_1/constraints.html
provides what we support for PK definition, which is that above.

> There should not be an ordering specified for the join table since duplicates

> primary key, since the JDO implementation should be able to figure out that
