Subject [jira] Commented: (OPENJPA-1200) Incorrect Entity is returned if ElementClassCriteria is not selected.
Date Mon, 24 May 2010 02:57:23 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-1200?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12870490#action_12870490

Ravi P Palacherla commented on OPENJPA-1200:
--------------------------------------------

I agree that ElementClassCriteria is the easy solution for this issue, but what is the purpose
of having DiscriminatorColumn ?
Doesn't it mean Book entity is distinguished by discriminatory value BOOKS and movie by MOVIES,
meaning when artist .getBooks() is called then the discriminatory value of books should only
be considered ?

One more reason for working on this issue is because customer claims the use case works on
other JPA provides, TopLink, without the need for proprietary annotations.

>From your previous notes, you are suggesting to revert the changes in this JIRA and use
ElementClassCriteria as a solution.
Also from OPENJPA-1398, it does not look like my changes cover all the scenarios properly.

So, I think the best thing to do here is to revert all the changes that went as part of this
JIRA and ask customer to use ElementClassCriteria.
Please confirm if my understanding is correct.
