Subject [jira] Updated: (JDO-241) JPOX returns wrong query result for non-extent queries.
Date Mon, 19 Dec 2005 20:30:32 GMT
     [ http://issues.apache.org/jira/browse/JDO-241?page=all ]

Michael Bouschen updated JDO-241:
---------------------------------

    Attachment: JDO-241.patch

Attached you find a patch for review.

As Andy pointed out, support for queries over transient instances is optional. The patch changes
the memory collection used as query candidates to include persistent instances. The test case
still does not succeed, because JPOX seems to eliminate duplicates for a memory collection
query with result specified as "this".
