Declare 'extent' which is not a subclass or implements interface
----------------------------------------------------------------
Key: OJB-82
URL: http://issues.apache.org/jira/browse/OJB-82
Project: OJB
Type: Bug
Components: ODMG-API, PB-API
Versions: 1.0.3
Reporter: Armin Waibel
In documentation section 'Extents' the following feature is listed
<snip>
Why is it necessary to explicitely declare which classes implement an interface
and which classes are derived from a baseclass?
...
In other cases it may be neccessary to treat certain classes as implementors of
an interface or as derived from a base even if they are not.
As an example, you will find that the ClassDescriptor for class
org.apache.ojb.broker.Article in the repository.xml contains an entry declaring
class CdArticle as a derived class:
</snip>
http://db.apache.org/ojb/docu/guides/advanced-technique.html#Extents
Currently this doesn't work because of a workaround in
QueryReferenceBroker#getCollectionByQuery which is used to filter out 'wrong'
objects returned by queries including a "table per class hierarchy" (using
ojbConcreteClass column).
