[jira] Commented: (JDO-241) JPOX returns wrong query result for non-extent queries.
[ http://issues.apache.org/jira/browse/JDO-241?page=comments#action_12360498 ]
Andy Jefferson commented on JDO-241:
------------------------------------
If you look at the test you find that the "candidate collection" passed in is of transient instances which hence have no identity (or at least JDOHelper.getObjectId() returns null). You are expecting the JDO implementation to find these instances without allowing it to know their identities ? Hmmmm
To quote the spec [14.6] :
<spec>
For portability, the elements in the collection must be persistent instances associated with the same
PersistenceManager as the Query instance. An implementation might support transient instances in the collection.
</spec>
I notice that the second sentence here has a word "might". Hence the test cannot impose the restriction since its an optional feature.
