[ http://issues.apache.org/jira/browse/OJB-62?page=all ]
Armin Waibel resolved OJB-62:
-----------------------------
Fix Version: 1.0.4
Resolution: Cannot Reproduce
I can't reproduce this issue with latest from CVS (1.0.4). Add new tests
ExtentAwarePathExpressionsTest#testAddClassPathOnQuery_1 and ..._2
The query is build against class Topic which has a subclass TopicExt:
<class-descriptor class="org.apache.ojb.broker.Topic" table="TOPIC">
<extent-class class-ref="org.apache.ojb.broker.TopicExt"/>
</class-descriptor>
Criteria criteria = new Criteria();
criteria.addLike("qualifiers.importance", "impor%");
QueryByCriteria query = QueryFactory.newQuery(BaseContentImpl.class, criteria,
true);
query.addPathClass("qualifiers", Topic.class);
List content = (List) broker.getCollectionByQuery(query);
> addPathClass in QueryByCriteria does not consider inheritance

> URL: http://issues.apache.org/jira/browse/OJB-62

> Type: Bug
> Components: PB-API

> I guess there is a bug in the addPathClass method. Orirginally I posted it on
> the mailing list and then you requested me to submit a new bug on this
> website:
> here is the code that I have
> public static Collection findModelsByAuthorsName(String aName) {
> PersistenceBroker broker =
> PersistenceBrokerFactory.defaultPersistenceBroker();
> try{
> Criteria crit = new Criteria();
> crit.addLike("sources.author", aName);
> QueryByCriteria query = new QueryByCriteria(Model.class, crit, true);
> query.addPathClass("sources", Citation.class);
> return broker.getCollectionByQuery(query);
> } finally {
> broker.close();
> }
> }
> when I run it I get an error (below). The problem is that Citation is a
> superclass that has a number of classes that implement it. If instead of
> Citation I use OJBCitation (which is not extended by any class) then
> everything works fine.
> Here is the definition of Citation:
> here is what I have:
> <class-descriptor class="edu.uci.ics.sigmoid.Citation">
> <extent-class class-ref="edu.uci.ics.sigmoid.OJBCitation" />
> <extent-class class-ref="edu.uci.ics.sigmoid.Article" />
