This seems to be what the spec says, so I will change the test, adding a new int field and corresponding column by which to order the List elements.
In this test case order information will be contained in a database column only, not in a field of the class.
I checked in changes to the .orm and .sql files (revision: 453382). There are two issues:
(1) When using the mapped-by ATTRIBUTE of the employees field, as I did in the case of datastore identity, I get javax.jdo.JDODataStoreException: Clear request failed : UPDATE datastoreidentity10.PERSONS SET DEPARTMENT = NULL, ORDER_COL = NULL WHERE DEPARTMENT = ? at org.jpox.store.rdbms.scostore.FKListStore.clear(FKListStore.java:1171) ... ERROR 23502: Column 'ORDER_COL' cannot accept a NULL value. at org.apache.derby.iapi.error.StandardException.newException(Unknown Source) ... (2) When using the mapped-by ELEMENT of the employees field, as I did in the case of application identity, I get ... ERROR 42X14: 'EMPLOYEES_ID_OWN' is not a column in table or VTI 'APPLICATIONIDENTITY10.PERSONS'. I used different syntax for the two identity types simply to illustrate the two problems in one check-in. They should be equivalent. When the problems are resolved, we can choose one syntax to use for both cases.

Hi Michelle,
the datastoreidentity case is fixed. JPOX used to use NULL as the value of the order column when the element is not in the List. CVS now uses -1 so can be used with non-nullable order columns (which yours is) and the test passes the applicationidentity case uses some "<element mapped-by=...>" syntax. I dont even remember this being discussed in the EG. "<order mapped-by=...>" was added for the specific case of wanting to use a particular field in the element for ordering. Specifying mapped-by on element for a List makes no sense to me since if the user wants the relation to be bidirectional they would use "<field mapped-by=...>". I see that it is in the DTD, but since we dont understand its potential use-case JPOX doesnt even parse that attribute. The mapped-by on "key" and "value" ARE of use since those cases are for specifying whether the key is stored in the value or the value is stored in the key of a map. The mapped-by on "order" IS of use since it allows the use of n (int-based) field in the element as the ordering. Can someone please clarify what this "<element mapped-by=...>" is for that "<field mapped-by=...>" isnt for ? "<element mapped-by=...>" and "<field mapped-by=...>" are equivalent ways of writing the same information. The user has a choice of where to put the attribute. Because this issue is peripheral to the test, and isn't terribly important anyway, I will change the test to use <field mapped-by>. If you want to pursue this question, you could bring it up with the Expert Group.

JPOX fails new test CompletenessTestList, configuration companyListWithoutJoin
<order column="HIREDATE"/>
This means that your ordering column (consistent with section 18.4 of the JDO2 spec) has to be integer-based
<spec>
The java type for the column mapped to an order element is assumed to be int.
</spec>
and HIREDATE is date-based.
Did you mean to use "mapped-by" in the Metadata to use an existing field in the Employee class to handle the list ordering? JPOX only supports integer-based fields for ordering currently.
