Problem with application id and extents

Question

Hi, I've run into what may be a bug, so I wanted to run it by your group.
I have a class that is using application identity and contains a
collection of strings. When I load each instance of the class, the
collection is filled in, however, when I load all the instances using
getExtent(), the collections are not filled in.
Thanks
The relevant part of the .jdo file is:
<class name="KeywordInfo" objectid-class="KeywordInfo$KeywordInfoJDOId">
<extension vendor-name="kodo" key="detachable" value="true"/>
<field name="idstr" primary-key="true" default-fetch-group="true"/>
</field>
<field name="jdoChoices" default-fetch-group="true">
<collection element-type="String"/>
<extension vendor-name="kodo" key="element-dependent" value="true"/>
</field>
</class>
The .mapping file is:
<class name="KeywordInfo">
<jdbc-class-map type="base" table="CATADMIN.MPM_KEY_INFO"/>
<jdbc-version-ind type="version-number" column="JDOLOCKX"/>
<field name="idstr">
<jdbc-field-map type="value" column="IDSTR"/>
</field>
<field name="jdoChoices">
<jdbc-field-map type="collection" element-column="ELEMENT"
order-column="JDOCHOICES_ORDER" ref-column.IDSTR="IDSTR"
table="CATADMIN.MPM_K_JDOCHOICES"/>
</field>
</class>
When I load a single instance, I get the following sql trace:
SELECT t0.JDOLOCKX, t0.DBIDX, t0.DESCRIPTIONX, t0.HASUNITSX, t0.IDSTR,
t0.ISDATAKEYWORDX, t0.ISDISPLAYABLEX, t0.ISEDITABLEX, t0.ISFACTOR,
t0.ISNULLVALUEALLOWEDX, t0.ISREQVALUEINCHOICESX, t0.JDODEFAULTVALUEX,
t0.JDOUNITX, t0.JDOVALUETYPEX, t0.KEYWORDX, t0.KEYWORDTYPEX, t0.REGEXP,
t1.IDSTR, t1.JDOCHOICES_ORDER, t1.ELEMENT FROM CATADMIN.MPM_KEY_INFO t0,
CATADMIN.MPM_K_JDOCHOICES t1 WHERE t0.IDSTR = ? AND t0.IDSTR = t1.IDSTR(+)
ORDER BY t1.IDSTR ASC, t1.JDOCHOICES_ORDER ASC [params=(String)
BDT:test111b]
When I load the extent, I get the following:
6549 DEBUG [main] jdbc.SQL - <t 6151022, conn 9992755> [0 ms] executing
prepstmnt 19940306 SELECT DISTINCT t0.IDSTR, t1.JDOCHOICES_ORDER,

Just tried it and got the same SQL (below).
SELECT DISTINCT t0.IDSTR, t1.JDOCHOICES_ORDER, t1.ELEMENT FROM
CATADMIN.MPM_KEY_INFO t0, CATADMIN.MPM_K_JDOCHOICES t1 WHERE t0.IDSTR IN
(?, ?, ?, ?, ?, ?, ?, ?, ?, ?) AND t0.IDSTR = t1.IDSTR ORDER BY t0.IDSTR
ASC, t1.JDOCHOICES_ORDER ASC [params=(String) BDT:13303055, (String)
BDT:test111b, (String) BDT:5606643, (String) BDT:5606644, (String)
BDT:5606645, (String) BDT:5606646, (String) BDT:5606647, (String)
BDT:5606648, (String) BDT:5606649, (String) BDT:5606650]

Extent iteration is slightly different than other fetching. Does using
an empty query pm.newQuery (Person.class, "") change the SQL?
