Andy Jefferson commented on JDO-241: ------------------------------------ Hmmmm. You call setCandidates() and pass in the same object twice and so you expect the query to return dups ? Sounds unintuitive to me. The query specifies that some object is a candidate for being returned (twice) and that, to me at least, means that we allow the selected candidates be part of the result - and the object is part of the result. The basic query says return all Person objects. I see "candidates" as a further filter only ... not some way of saying "return me the same thing twice, or three times depending on how many times I put it in my candidates list". > JPOX returns wrong query result for non-extent queries. > ------------------------------------------------------- > > Key: JDO-241 > URL: http://issues.apache.org/jira/browse/JDO-241 > Project: JDO > Type: Bug > Components: tck20 > Reporter: Michael Watzek > Assignee: Erik Bengtson > Attachments: JDO-241.patch > > Test case DistinctCandidateInstances fails because JPOX returns an empty > collection for the query below.
